Sine wave inverter basic working principle

Sine wave inverter with advanced MPU (microprocessor) intelligent control, core and power IC devices used in all high-quality imported components, so that the peripheral circuit structure is simple and rigorous, control methods and control strategies flexible and powerful. DC DC-AC sine wave output, load your electrical interference was completely damaged. Is the best choice with inductive loads, the application of electromagnetic induction principle of making high-power electrical products, such as motors, compressors, relays, fluorescent lamps, and so on. These products need a startup than to maintain normal operation (about 3-7 times) of the desired current much larger starting current. For example, during the normal operation of a refrigerator 150 watts of power, the starting power up to 1000 watts or more. Further, since the inductive load in an instant power or disconnect the power, it will produce a counter electromotive force voltage, peak voltage is much larger than that of the 6000w power inverter can withstand voltage, it can easily lead to the inverter instantaneous overload affecting the life of the inverter. Thus, higher electrical power supply waveform such requirements.
