【Abstract】 A novel SPWM control circuit for an inverter power supply is proposed in the paper. It has quite good characteristics and is quite simple, reliable and versatible. The concept of "alternative instantaneous negative feedback" is introduced in the circuit, so the system has a lower total distortion of the output of the inverter.更多还原
