Abstract :
A four level inverter based induction motor drive system utilizing an active four level rectifier has been proposed. This paper outlines the strategy for the rectifier control of such a system. A new switching scheme for concurrently balancing the link voltages and drawing unity power factor input currents is introduced. The proposed control scheme is dynamic and does not use lookup tables. Simulation results are used to verify the performance for a variety of load conditions
