The proposed algorithm consists of forbidding unnecessary triggers for the inverter switches and do not need any additional circuits and off-line experimental measurement. The realization of algrithm is very simple, the harmonics in output waveform are small, and the algrithm resoves the pulsant when the system works at the low frequency. The proposed algorithm was applied to a PM synchronous motor drive system.
