| Abstract: | This paper is a simulation and experimental study of ful1-bridge inverters.It can effectively reduce the THD of output voltage by using single polarity double frequency SPWM modulation model,if the switch frequency of the inverter is low.This method can improve the quality of the output voltage waveform,reduce the filter parameters of the main circuit output a lot,and enhance the efficiency of inverters. |
