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 levelcross H bridge MLI were performed and presented.

This study aimed to develop a three-phase permanent-magnet synchronous motor drive system with improvement in current harmonics. Considering the harmonic components in the induced electromotive force of a permanent-magnet synchronous motor, the offline response of the induced electromotive force (EMF) was measured for fast Fourier analysis, the main harmonic components were obtained, and the voltage required to reduce the current harmonic components in the corresponding direct (d-axis) and quadrature (q-axis) axes was calculated. In the closed-loop control of the direct axis and quadrature axis current in the rotor reference frame, the compensation amount of the induced EMF with harmonic components was added. Compared with the online adjustment of current harmonic injection, this simplifies the control strategy. The drive system used a 32-bit digital signal processor (DSP) TMS320F28069 as the control core, the control strategies were implemented in software, and a resolver with a resolver-to-digital converter (RDC) was used for the feedback of angular position and speed. The actual measurement results of the current harmonic improvement control show that the total harmonic distortion of the three-phase current was reduced from 5.30% to 2.31%, and the electromagnetic torque ripple was reduced from 15.28% to 5.98%. The actual measurement results verify the feasibility of this method.
