Due to the dead-time setting, the switch tube can't break at ideal moment, which leads to the output waveforms distortion of inverter. In order to improve the waveform, dead-time effect needs to be compensated. Taken advance-off mode as an example, the influence of dead time on selective harmonic elimination pulse width modulation(SHEPWM) was analyzed in this paper. The curves of amplitude and total harmonic distortion(THD) at different dead time were given. A novel dead time compensation strategy was propo...
