speedcontroller Dead time effects Of IGBTs

Posted on Feb 6, 2014

Project to control single phase ac induction motor in which I planned to use two IGBTs, one for switching the PWM to the motor (for AC chopping, PWM frequency is fixed @16khz) and one for freewheeling the motor. A symbolic circuit is included here: I know the dead time of IGBTs is going to have some effect on the system. I want to

know how worst the system is going to be effected because of this dead time and what are the remedies with respect to hardware and software.
