Abstract :
This paper presents the simulation results of two types of control system for an induction machine, fed by a PWM current source inverter with a capacitive output filter. The vector control scheme was applied in both cases. In one system, control of stator phase current vector takes place through an intermediate signal of the stator current frequency. This signal is determined by the load angle proportional-integral (PI) controller. In the second system, stator phase current is directly controlled, thanks to synchronization of the modulator with respect to stator flux. Though the output filter capacitors of PWM current source inverters (CSI) causes some difficulties in forcing rapid changes in machine currents and voltages, the systems presented herein are characterized by good dynamic properties
