Abstract :
In this paper, a novel speed control of a single phase induction motor is proposed using a modified inverter. Three MOSFETs are used for controlling the flux linkage of a single phase transformer, its secondary winding is connected in series with the motor. On-line bang-bang speed control of a motor scheme is implemented using a microprocessor to derive the inverter. A mathematical model for the single-phase induction motor is presented, which is used to build up a simulation program for a certain desired speed. Experimental results have been carried out to investigate the motor performance with the controller. Good agreement has been obtained between simulation and experimental results
