The Output Waveform Control Methods of Auxiliary Voltage Source Inverter

This paper summarizes many of the inverter output waveform control methods at present and divides them into the control method based on cycle and the control method of instantaneous feedback. The control method based on cycle uses periodic compensation of error to achieve the steady without static error, mainly including the repetitive control and harmonic feedback control. Instantaneous feedback control method uses rapid detection to correct the inverter output waveform, mainly including PID control of single loop, double-loop control, deadbeat control, and hysteresis control. In order to achieve the ideal waveform control, the most promising method was proposed after analyzing the characteristics of those methods.
