Abstract: Power electronic technology made possible to evolve inverter fed electric drives. Permanent magnet synchronous motors (PMSM) are in much importance and are used often due to its performance characteristics. PMSM gives less noisy operation with faster and more efficient operation. PMSM needs a digital inverter for its operation. The paper analyzes nine-level inverter fed PMSM drive. Multi-carrier level-shifted technique is used to generate control pulses. Simulation work of the proposed concept is carried out and the results are presented using MATLAB/SIMULINK software.
