Abstract :
This paper presents the generation of "dead-time" in switching signals of a PWM AC chopper. It also presents the effects of dead-time in the output voltage of such converters. Comparisons between the effects of dead-time in inverters and in the PWM AC chopper are made. An open-loop compensation method is proposed and verified.
