Abstract: The Permanent Magnet Synchronous Motors (PMSM) are replacing the asynchronous motors in traction applications. The efficiency of the motor depends on the efficiency of the inverter drive circuit. Several Multi-Level Inverters (MLI) are discussed. To improve the performance of PMSM, Multi-Module Multi Level Cascaded Inverter (MMCMLI) is designed with phase disposition modulation algorithm. The MMCMLI is powered by solar energy with maximum point tracking. The entire design is simulated in Matlab/Simulink. The incremental conductance maximum power point tracking control is discussed in detail. The design of 3, 5, 7 and 9 level MMCMLI is shown with the phase disposition modulation algorithm. Finally the designed converters are combined with the battery bank and PMSM. The performance of PMSM with 3, 5, 7 and 9 level inverter is discussed. Also the phase current and speed variation of PMSM at different operating frequencies below and above the rated frequencies is analyzed. The voltage and current THD analysis of different level of the MMCMLI shows that the voltage harmonics decreases with increase in the level whereas the current harmonics stays at an average level which increases the stability of motor operation at frequencies below the rated frequency.
