This paper describes the simulation of a single phase induction motor by ac chopper, which uses asymmetrical PWM technique to reduce the harmonics present in the motor current. The flow of power to the motor is controlled by a switching action of the power switches, which thereby control the speed of the induction motor. In this paper ac chopper module uses the IGBT as a power switch because of having more advantages over other power switches(MOSFET,THYRISTOR ETC) The main objectives of our project are to maintain the speed constant at different load condition. The simulation is carried out in MATLAB/SIMULINK with split phase induction motor.
