Although the SPWM modulation can obtain a good sine wave, the harmonic problem can not be ignored. The improvement of output voltage and waveform control of single-phase inverter based on SPWM modulation is studied. The addition of a three harmonic component method in fundamental sine wave modulation reference, Matlab / simulink is used to simulate the traditional SPWM single-phase inverter output and the improved algorithm. The results show that the use of improved SPWM control algorithm for modulation of the inverter output, the output fundamental voltage increases obviously and the output v...
