    I'm working on a 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 and 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. what will happen if i completely ignore the dead time . Any help would be deeply appreciated.
