12 volt power inverters Power inverter Profile

Inverter (inverter) is the DC power (battery, storage battery) into split phase pure sine wave inverter‍ alternating current (typically 220v or 380V50HZ sine or square wave). Emergency power, the general is to reverse into 220v DC bottle exchange. 

The power inverter is 12V or 24V DC power (battery, storage battery) into alternating current (typically 220v50HZ sine or square wave), typically used for substations, changed me, to provide emergency power for the high-voltage cabinet cabinet, this products are high-voltage inverter. 

Popular speaking, the inverter is a direct inverter bypass switch‍ current (DC) into alternating current (AC) devices. It consists of inverter bridge, and filter control logic path component.

12v power inverter Automotive Power

Car power inverter power called, is a way to convert the DC power DC12V and AC220V AC mains the same, for general electrical use, is a convenient power converters, as commonly 4000w power inverter‍ used in the automotive named. General use car power car battery or cigarette lighter power supply, the first such low-voltage direct current is converted to DC 265V or so; then is the real transformation stage, it will transform high voltage DC to AC 220V, 50Hz for. With the car power, you can put all the family moved to the car using small appliances such as mobile phones, laptop computers, digital cameras, car refrigerators, cameras, DVD, etc., thus making the car there is a feeling of home away from home . Since its launch, many limitations of using those appliances in the car will no longer exist, people can really enjoy, "and family-friendly, connected with the world" feeling. 

Car power not only apply to vehicle systems, as long as there are occasions DC12V DC power supply, power inverter can be used, will convert DC12V AC220V AC, bring convenience to people's lives. Car power fully take into account the external environment, when an overload or short circuit protection will be automatically shut down. The output voltage of the power supply through the feedback confirmed the car itself can make the voltage stability, voltage variation is less than the rated load and 10V. It should be noted that the purpose of the automobile is the output power and split phase pure sine wave inverter‍ the same mains voltage to meet the needs of appliances, automotive power actually output is an analog sine wave and the sine wave of the mains is true, the two slightly different , generally do not affect the use, it is the working principle of automotive power decision.

12v power inverter Modified sine wave inverter Precautions

Modified sine wave inverter should avoid "inductive load." In layman's terms, that the application of electromagnetic induction principle of making high-power electrical products, 2000w inverter charger‍ such as motors, compressors, relays, fluorescent lights, and so on. These products need when starting a ratio to maintain normal operation (about 5-7 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 is much larger than this car inverter can withstand voltage, can easily cause car inverter instantaneous overload, the life impact of the inverter. 

When you use an ordinary multimeter to measure quasi-sine wave (modified sine wave) car inverter AC output voltage 20V display playful than 220 or so. 

Cause problems when running sophisticated industrial inverters‍ equipment, can also cause high-frequency interference to communications equipment.

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.
