The function of the inverter is to convert direct current into alternating current, it is composed of inverter bridge, SPWM wave module! Drive module and filter circuit, SPWM inverter circuit is the key to generate pure sine wave. The generation of SPWM wave module has always been a research focus. SPWM is the pulse width modulation technology, which is also the pulse waveform with variable duty cycle. PWM control technology is based on this conclusion. The semiconductor switching device on and off control, so that the output end of a series of equal amplitude and width of the pulse is not equal! To obtain the required waveform equivalent, when performing pulse width modulation! If the duty cycle of pulse series is arranged according to sinusoidal law, then the output voltage can be filtered to get sinusoidal waveform! At the same time, the harmonic component of load current is greatly reduced, which is called sinusoidal pulse width modulation.
