Mitigating the dead-time effects on harmonics spectrum of inverter waveform by the confined band vsfpwm technique

The dead-time is necessary to be inserted between the gates drive pulses of the two power electronic switches in a one leg of any inverter to avoid a short circuit in the leg and the DC supply as well. However, adding the dead-time increases the low order harmonics of the output voltage/current wave...
