Abstract

Modeling and simulation of fifteen level cross H bridge multilevel(ML) inverter fed three-phase PMSM presented in this paper. In order to overcome the setbacks of an inverter via switching losses and harmonic disturbance, Cross H bridge MLI topology is developed. The number of switches and DC voltages considered in this model are much inferior to other inverter topologies. The topology presented in the paper has better output and lower harmonic distortion (THD). Also, Permanent Magnet Synchronous Motor (PMSM) have significant advantages over other drives. Analysis and Simulations of 5, 9 and 15 level cross H bridge MLI were performed and presented.
