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 pure sine wave 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 220 volt power inverters‍ 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 car power supply output and the same mains voltage to meet the needs of appliances , automotive power actually output is an analog 12v inverter charger‍ 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 .

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.

It refers to the ability of the regulator output voltage of the inverter . 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 What is the inverter

What is the inverter, what role it 

Simply put, the inverter is a low-voltage inverter bypass switch‍ (12 or 24 volt) DC into 220 volts AC electronic devices. Because we usually rectified to 220 volts AC into DC to use, and the role of the inverter on the contrary, hence the name. We are in a "mobile" era, mobile office, mobile communications, mobile leisure and entertainment. In moving state, people not only need low voltage direct current from a battery or battery supply, but we need DC AC power inverters‍ more indispensable in our daily environment 220 volts AC inverter to meet us this demand.
