Abstract :
The paper describes topology and control of three-phase DC-to-AC converter for variable speed cage induction machine. The proposed DC-to-AC four-quadrant converter provides wide range frequency and amplitude sinusoidal voltage. The sinusoidal voltage is produces by PWM modulation passive LC filter and control system. The multiloop controller consists of voltage controller and a current controller. Experimental results have been given to verify the proposed topology and the control scheme. The results confirm the practical feasibility of the topology and control system
