Enhanced Topology of Induction Motor Drive

This paper proposed a new converter topology to drive induction motors. the proposed topology can boost the dclink input voltage in case of dc link voltage shortage without any additional converter. this converter employs twoadditional switches and one capacitor in each phase compared to conventional converters. moreover, this newtopology brings additional advantages such as less torque and current ripples and lower switching loss. after adiscussion of the basic principles of operation, the dynamics of the converter is developed for control purposes.simulation results are given to illustrate the associated advantages of the proposed converter.
