Circuit principle 12v to 110v inverter

Circuit principle 12v to 110v inverter: The power inverter field effect transistor as the inverter device. Car battery for power supply. Therefore, when the input voltage is 12 volts DC. The output voltage is 100V AC's. However, the input and output voltage is not limited to this. You can use any voltage. They rely on transformers. The output is a square wave. According to experience, this circuit approximately 100W power. Circuit must be installed by a fuse, because too much input current flows, the oscillator is stopped.

What is the difference between the inverter and the inverter

The inverter also known as power converter is capable of (battery, storage battery) is converted to DC and mains same AC220V, 50HZ AC, for general electrical use.
The inverter is the use of power semiconductor devices will be the role off frequency to another frequency power conversion power control device.
The effect is to change the drive AC motor supply frequency and amplitude, thereby changing the magnetic field of its movement cycle, to achieve the purpose of controlling the motor speed.
Inverter works are first put through the rectifier bridge rectifier frequency power to DC and then into different frequency AC power supplied to the motor through the 1000w with charger inverter.
The biggest difference between the inverter and the inverter is part of the frequency converter must be adjusted, and the inverter output as long as there is a fixed frequency on the line

How to determine the quality of the inverter

Since the inverter has been increasing use, but when people do not know how to buy an inverter to judge the quality of the inverter, here are a few points to attention:
First, instead of using a modified sine wave inverter 5000w solar inverter, since the modified sine wave inverter circuit is relatively simple, cost is low, but modified sine wave inverter with a carrying capacity was poor, small range, especially such as motors, printers, pumps and the like, it is easy to damage, this kind of judgment is very simple, that price is less than 1 yuan / W is likely to be modified sine wave inverter;
Second, are the sine wave inverter, and some manufacturers subtractive process, but also caused decline in the quality of the inverter, such as internal circuit boards must be moisture treatment; housing must meet certain thickness; noise during operation; overload, short circuit protection and alarm ; over-temperature protection; and meticulous self-repair aging and so on.
Third, no matter for what areas of the inverter, are automotive, shipbuilding, telecommunications, electricity, or home, is a very strict, very demanding production process.

12V turn 220V inverter works

First, it divides a DC voltage to the preamp IC power generating a control signal KHZ level all the way to the front stage power tube driven by a control signal so that the high-frequency switching power transistors continue to produce low-voltage high-frequency transformer primary alternating current (AC although this time voltage is low, but the frequency is very high, the purpose is to make the post-stage transformer generates a voltage proportional to the voltage of a high frequency pre-and post-stage output, of course, but also in power tube can withstand the frequency range) through high frequency transformer output frequency alternating current and then after fast recovery diode full bridge rectifier output a high frequency of several hundred V DC power to the rear stage of control signal 50HZ about then generated by the post-stage IC to control the post-stage power tube work and output 220V50HZ ac
Of course, a complete 12v car inverter also need some protection circuits such as high and low temperature protection Input voltage overload protection and filter circuits in high-frequency circuit filter is also important to be prone to a number of high-frequency interference and parasitic coupling it is necessary to filter circuit to filter In addition to these factors to increase the stability of the circuit

Function PV inverter

3000w solar inverter only has the direct exchange conversion function, but also has to maximize the performance of the solar cell functions and system fault protection. Summed up automatic operation and shutdown functions, maximum power tracking control, anti-alone operation function (and network systems), automatic voltage regulation function (and network systems), the DC detection (grid systems), the DC ground fault detection function (grid systems). Here a brief stop function and automatic operation and maximum power tracking control. 1, automatic operation and shutdown morning after sunrise, gradually increase the intensity of solar radiation, solar cell output also increased, when the work required to achieve the output power of the inverter, the inverter starts running automatically. After entering operation, the inverter will always monitor the output of solar cell modules, as long as the desired output power of the solar cell module output power is greater than the inverter operation, the inverter will continue to run until sunset down, even rainy days The inverter can be run. When the solar cell module output decreases, the inverter output is close to 0, the inverter will form a standby state. 2, the maximum power output of the solar cell module tracking control function is varies with the intensity of solar radiation and the solar cell module itself temperature (chip temperature). In addition, as the solar cell module having a voltage increases with the current decline of characteristics, so there can get the best operating point of maximum power. Solar radiation intensity is changing, obviously the optimum operating point is changing. In contrast to these changes, and always let the operating point of the solar cell module at the maximum power point, the system always get the maximum power output from the solar cell module, this control is the maximum power tracking control. The most important feature of the solar inverter systems is included in the maximum power point tracking (MPPT) this function.

Sine wave and modified sine wave

Sine wave power inverter output is the same as the grid we use every day even better sine wave AC, because it does not exist power of electromagnetic pollution. Square wave inverter output power is the poor quality of the square wave AC, its positive maximum to negative almost at the same time generate the maximum, so causing severe destabilizing effects on the load and the power inverter itself. Meanwhile, the load is low, only 40-60% of the rated load, not with inductive load. As the load carried is too large, square-wave current third harmonic components contained will flow into the capacitive load current increases, severe damage to the load of the power supply filter capacitor. In response to these shortcomings, in recent years there has been quasi-sine wave (or modified sine wave, modified sine wave, sine-wave, etc.) 48v to 220v power inverter, the output waveform from the positive to the negative maximum value between the maximum value there is an intervals, using the results improved, but is still quasi-sine wave by the broken line, belonging to a square wave category, continuity is not good, and there is a dead zone. All in all, sine wave power inverter provides high-quality alternating current, can bring any kind of load, but the technical requirements and costs are high. However, some sophisticated electronic equipment and appliances must use inductive load class sine wave power inverter. Otherwise, ranging might cause related electronic device is not working properly, it caused heavy equipment and power inverter damage or shorten its expected life. Quasi-sine wave power inverters meet our daily most of the electricity demand, high efficiency, low noise.

Effect inverter

Simply put, the inverter is a kind of low-voltage (12 or 24 volts or 48 volts) direct current into 220 volts AC electronic devices. Because we usually 220 volts AC into DC rectifier to use, and the role of the 500w charge inverter on the contrary, hence the name. We are in a "mobile" era, mobile office, mobile communications, mobile leisure and entertainment. In a moving state, the people not only need low-voltage direct current from the battery or battery supply, but also an essential need in our everyday environment 220 volts AC inverter to meet us this demand. Inverter free two main categories, one is sine wave inverter, and the other is a square wave inverter. Sine wave inverter output is the same as the grid we use every day even better sine wave AC, because it does not exist power of electromagnetic pollution. Square wave inverter output is the poor quality of the square wave AC, its positive maximum to negative almost at the same time generate the maximum, so causing severe destabilizing effects on the load and the inverter itself. Meanwhile, the load is low, only 40-60% of the rated load, not with inductive load (explained in detail below article). As the load carried is too large, square-wave current third harmonic components contained will flow into the capacitive load current increases, severe damage to the load of the power supply filter capacitor. In response to these shortcomings, in recent years there has been quasi-sine wave (or modified sine wave, modified sine wave, sine-wave, etc.) of the inverter, the output waveform from the positive maximum to the negative maximum value between the time there is a spacing effect has improved, but is still quasi-sine wave is composed of a line, belonging to a square wave areas, poor continuity. In conclusion, sine wave inverter providing high-quality alternating current, can bring any kind of load, but the technical requirements and costs are high. Quasi-sine wave inverter can meet most of our electricity demand, high efficiency, low noise, moderate prices, and thus become the market mainstream. Square wave inverters produced using simple multivibrator, its technology is the level of the 1950s, will gradually withdraw from the market. According to the power inverter hair, divided into coal inverter, solar inverter, wind inverter, nuclear inverter. Depending on the application, divided into independent control of the inverter, and inverter. Inverter efficiency as described above, the inverter work itself should consume some power, therefore, its input power is greater than its output power. Efficiency of the inverter that is inverter output power and input power ratio. If a single inverter 100 watts of DC power input, the output of the 90-watt AC power, then its efficiency is 90%. The world solar inverters, high efficiency in Europe and America, the European standard is 97.2%, but the price is more expensive, the domestic market is only Shenzhen Green New Energy Co., the largest pure sine wave inverter efficiency can reach 95% or more, domestic other inverter efficiency is 90% or less. In addition to efficiency, select the inverter waveform is also very important.

The difference between pure sine wave and sine repair

Inverter waveform is divided into two categories, one is sine wave inverter (ie, pure sine wave inverter), the other is modified sine wave inverter (modified sine wave). Sine wave inverter output is the same as the grid we use every day even better sine wave AC, because it does not exist power of electromagnetic pollution. Modified sine wave (or modified sine wave, quasi sine wave, sine-wave, etc.) of the 8000w high frequnency inverter, the output waveform from the positive maximum to the negative maximum there is a time interval between, improvement effect, but quasi-sine wave is still made polylines, still belongs to the category square wave, continuity is not good, and there is a dead zone. Modified sine wave inverter generally use non-isolated coupling circuit, and pure sine wave inverter with isolated coupling circuit design. Its prices vary a lot.

Use car inverter note:

1, should be strictly in accordance with the user's manual to the use of an inverter;
2, when the inverter output voltage 220v AC 220v and this is in a small space and in a movable state, to be placed in a more secure place to prevent electric shock;
3, when not in use, the best cut off the input power supply;
4. Do not place the battery power inverter near direct sunlight or warm air outlet;
5, when the inverter operation will generate heat, so do not place items on or near the top;

Difference sine wave inverter with inverter that where?

Check the information in time will find that sine wave inverter with inverter is met, but in fact 1000w with charger inverter with the inverter is not the same as the nature of it?

So now the inverter is already being widely used in many place.
The difference between the sine wave inverter with inverter that more sine wave inverter has perfect function, sine wave inverter only has the inverter also features an even higher level than the electric inverters!
The inverter is used in a general postal system, and the scope sine wave inverter can be used more widely.

Power sine wave inverter | power inverter | inverter

Inverter types are very much alone in the classification model which has dozens of words, but the inverter different models of electric power and voltage are not the same, the use is not the same place.
In so many of the 8000w high frequnency inverter which is the most powerful power sine wave inverter, because in today's domestic market is more heavy industry manufacturers;
These plants need a lot of power to the general solar inverters or inverter is unable to fully meet these power plants!
The power sine wave inverter factory fully meet the demand for electricity, because power sine wave inverter voltage and electric power are very high, and the power sine wave inverter current is very stable, with up It is very safe.
Power sine wave inverters are used under normal circumstances some large factories, aerospace, companies and a large number of these uninterruptible power supply place!
The power sine wave inverter with power inverters also a big difference in terms of view of power sine wave inverter power inverter with relative little different, but the nature and the structure there is a very great distinction, the 800w power inverter is without power sine wave inverter electric power so much, but is widely sine wave inverter power than even wide power inverter.
Because the power inverter can generally applicable to a lot of power products, each inverter has been invented are its main features, and the use of local and voltage magnitude is not the same!
Choose a suitable own inverter is very important, particularly in the power sine wave inverter!

Inverter control strategy

PV 8000w high frequnency inverter to achieve and operation must be met: the output voltage with the same frequency and the same grid voltage amplitude of the output current with the grid voltage frequency and phase (power factor of 1), and its output should also meet the requirements of grid power quality . These are dependent on the effective control strategies 800w power inverter . PV grid inverter control is generally divided into two areas: the first one link to get the system power point, the photovoltaic array operating point; the first two aspects of the completion of photovoltaic 1000w with charger inverter systems on the grid tracking.
Meanwhile, to ensure the safe and effective photovoltaic inverter operates in direct and network status, the system must have a protective function and anti-islanding detection and control of.

Sower sinverter

These inverters’ high wattage output with low voltage input can save money if planning on using the inverters to power an air compressor on a fleet of construction vehicles, for example, because the business owner wouldn’t need to upgrade any truck’s standard 12 volt power system to 24 volt power inverters or 48v inverter in order to power the inverter.
Both inverters have the ability to withstand the locked rotor startup, or locked rotor amperage (LRA), of most air compressors and/or air conditioners. The 8000 watt can handle any LRA under 66 and 1000 watt power inverter can handle any LRA under 83 because of the inverters’ ca

Inverter 12V inverter (DC 12V to AC 220v inverter) principle and the production process described here (see figure) FET mainly by MOS, constitute ordinary power transformer. Its output power depends on the transformer and power MOS FET power, eliminating the cumbersome transformer winding, for the use of electronic enthusiasts amateur productions.12 volt power inverters The following describes the working principle of the inverter and the production process.
12V inverter principle here we will detail the inverter works. CD4069 inverter used here constitute six square wave signal generator. R1 is a compensation resistor circuit, the oscillation frequency due to the power supply for improving the voltage variation caused by instability. Oscillation circuit is completed by the charging and discharging of the capacitor C1. solar inverters

The oscillation frequency is f = 1 / 2.2RC. The maximum frequency of the circuit diagram for fmax = 1 / 2.2 × 3.3 × 103 × 2.2 × 10-6 = 62.6Hz; minimum frequency fmin = 1 / 2.2 × 4.3 × 103 × 2.2 × 10-6 = 48.0Hz. Because of the error components, the actual value will be slightly different. Other extra inverter input is grounded to avoid affecting other circuits.

12 volt power inverters

12V inverter performance test where test input power supply with low internal resistance, discharge current is large (typically greater than 100A) of the 12V car battery, can provide sufficient input power circuit. Test load
For ordinary light bulbs. The method of testing is by changing the size of the load, and this time was measured input current, voltage and output voltage. The test results are voltage and current curves of relationships. As can be seen, the output voltage decreases with increasing load, 300 watt power inverter consumption of the lamp voltage-dependent changes. We can also find out by calculating the relationship between the output voltage and power. But in fact due to the resistance of the light bulb will vary by plus changes in the voltage across the change, and the output voltage and current is not a sine wave, so this calculation can only be regarded as estimates. With a load of 60W light bulb, for example: assume that the lamp voltage does not vary with changes in the resistance to change. Because R lamp = V2 / W = 2102/60 = 735Ω, 500w power inverter when the voltage is 208V, W = V2 / R = 2082/735 = 58.9W. Thus can be converted into a voltage and power relations. Through testing, we found that when the output power of about 100W, the input current is 10A. Then the output voltage is 200V. Inverter power efficiency characteristics shown in Figure 15b.

12v inverter performance test where test input power supply with low internal resistance, discharge current is large (typically greater than 100A) of the 12V car battery, can provide sufficient input power circuit. Test load for an ordinary light bulb. The method of testing is by changing the size of the load, and this time was measured input current, voltage and output voltage. The test results are voltage and current curves of relationships. As can be seen, the output voltage decreases with increasing load, the power consumption of the lamp voltage-dependent changes. We can also find out by calculating the relationship between the output voltage and power. But in fact due to the resistance of the light bulb will vary by plus changes in the voltage across the change, and the output voltage and current is not a sine wave,power inverter so this calculation can only be regarded as estimates. With a load of 60W light bulb, for example: assume that the lamp voltage does not vary with changes in the resistance to change. Because R lamp = V2 / W = 2102/60 = 735Ω, so when the voltage is 208V, W = V2 / R = 2082/735 = 58.9W. Thus can be converted into a voltage and power relations. Through testing, we found that when the output power of about 100W, the input current is 10A. Then the output voltage is Solar power inverters. Inverter power efficiency characteristics shown in Figure 15b. When the inverter continuous 100W load, FET temperature graph.

12 volt power inverters harmonic distortion and the ability to output voltage stability

When independent inverter output waveform is a square wave and modified sine wave , the output current of the inverter , in addition to the fundamental but also have high harmonics , 12v to 220v inverter‍ harmonic current will generate additional losses in the eddy and other inductive loads , resulting in part severe fever , is not conducive to the safety of electrical equipment. Square wave inverter harmonic distortion of around 40% , generally apply only to a resistive load ; modified sine wave inverter harmonic distortion is less than 20% , suitable for the majority of the load ; sine wave inverter harmonics distortion is less than 3% , the waveform quality than the quality of the electricity grid fortunately , 220 volt power inverters‍ can be applied to all of the AC electrical loads.

PVS independent solar battery terminal voltage in the charging and discharging process volatile, often lead-acid battery terminal voltage fluctuations of up to about 30% of nominal voltage , the inverter which requires a better performance of the regulator , in a relatively wide DC input range guaranteed to work properly. Capacity due to the use of high-frequency inverter and pure sine wave inverter‍ secondary secondary -width-modulated regulator technology , so the relative frequency inverter has a better stability of the output voltage.

12 volt power inverters How should connect the inverter and the power supply and the load

A: The use of electrical appliances 150 watts to 150 watts can be high frequency inverter‍ directly plugged into the inverter plug the cigarette lighter socket after use. More than 150 watt inverter via alligator clips directly to the battery wires, the battery positive red wire, black wire to the battery negative (not reversed, remember!) If the battery power is far away from the place, connect the inverter principle is: an inverter with battery connections inverter charger 12V‍ should be as short as possible, and 220 VAC output lines longer anyway.

12 volt inverter What is "inductive load"

In layman's terms, that the application of electromagnetic cnbou sine wave inverters‍ induction principle of making high-power electrical products, such as motors, compressors, relays, fluorescent lights, and so on. These products need when starting a ratio to maintain normal operation (about 3-7 times) required a much larger current starting current. For example, a refrigerator power consumption during normal operation of about 150 watts, its starting power up to 1000 watts or more. In addition, due to the inductive load in an instant power or disconnect the power supply, will produce back-EMF voltage, peak voltage of this inverter can withstand far greater than the voltage value, it is easy to high frequency inverter‍ cause instantaneous inverter overload affect the service life of the inverter. Thus, higher electrical power supply waveform such requirements.

12v power inverter Divided by the output waveform, the inverter is divided into several categories

 The two main types, one is the sine wave inverter, and the other is a square wave inverter. Sine wave inverter output power is the same as we use every day or even better sine wave AC DC AC power inverters‍ power because it does not exist in the electromagnetic pollution. The square wave output of the inverter is the poor quality of the square wave alternating current, the positive maximum to the negative maximum value to almost simultaneously generated, so resulting in a dramatic effect on the instability of the inverter and the load itself. At the same time, its load capacity is poor, only 40-60% of the rated load, not with inductive load (explained in detail below article). If solar power inverter‍ the load carried by large, square-wave current third harmonic components contained enable capacitive currents flowing into the load increases, and in severe damage to the load of the power supply filter capacitor. For the above disadvantages, in recent years a quasi-sine wave (or modified sine wave, modified sine wave, sine-wave, etc.) of the inverter, the output waveform from the positive maximum to a negative maximum time between intervals, using the results improved, but is still quasi-sine wave by the broken line, belonging to the scope of the square wave, continuous bad. In conclusion, the sine wave inverter providing high-quality alternating current, can bring any kind of load, but the technical requirements and costs are high. Quasi-sine wave inverter can meet most of our electricity demand, high efficiency, low noise, moderate prices, and thus become the market mainstream products. Square wave inverters produced using simple multivibrator, which belongs to the level of cnbou sine wave inverters‍ technology in the 1950s, will gradually withdraw from the market.

12 volt power inverters Modified sine wave inverter Overview

Modified sine wave is relative to the sine wave is concerned, and now the mainstream of the inverter output waveform, is modified sine wave. The waveform of the inverter main two power sinverter‍ categories, one is a sine wave inverter (ie, pure sine wave inverter), and the other is a square wave inverter. Sine wave inverter output power is the same as we use every day or even better sine wave AC power because it does not exist in the electromagnetic pollution. 

The square wave output of the inverter is the poor quality of the square wave alternating current, the positive maximum to the negative maximum value to almost simultaneously generated, so resulting in a dramatic effect on the instability of the inverter and the load itself. At the same time, its load capacity is poor, only 40-60% of the rated load, not with inductive loads. If the load carried by large, square-wave current third harmonic components contained enable capacitive currents flowing into the load increases, and in severe damage to the load of the power supply filter capacitor. 

For the above disadvantages, in recent years a pure sine wave power inverter‍ modified sine wave (or modified sine wave, quasi sine wave, sine-wave, etc.) of the inverter, the output waveform from the positive maximum to a negative maximum time between intervals, using the results improved, but is still a sine wave correction by the broken line composed, still belongs to the scope of the square wave, the continuity is not good, and there is a dead zone (waveform diagram below). Modified sine wave inverters generally use non-isolated coupling circuit, and pure sine wave inverter with isolated coupling circuit design. Its price is also a lot of difference. Modified sine wave inverter switching power supply, not only eliminates the need for bulky power frequency transformer, but also greatly improve the efficiency of the inverter efficiency of 90%. 

Modified sine wave inverter switching PWM pulse width modulation to generate modified sine wave output, the inverter process, due to the use of a dedicated intelligent circuit and power FET, greatly reducing the power consumption of the system. And an increase in soft-start function, effectively ensuring the reliability of the inverter. If electricity is not very high quality, and it is able to meet the needs of most electrical equipment, but it still 2000w inverter charger‍ exists 20% harmonic distortion, a problem occurs when you run precision equipment, can also cause high frequency of communications equipment interference.
