The possibility of feeding a three phase induction motor by 60" two phase P.W.M. supply (by
means of four-switches inverter) is presented in this paper in order to minimize the cost of the
conventional three phase inverter (six-switched inverter). The main goal of this paper is to
implement the idea of the control system of a three phase induction motor fed by two
phase inverter using field oriented technique. The implemented control algorithm permits the
motor to operate under the dynamic and steady state conditions. Finally, simulated results of the
motor under control are presented.
