In traction system the choice of motor is very important, multipurpose motors are available in the market. By considering the motor parameter like high power to weight ratio, high torque to current ratio with that high efficiency and robustness. Owing all the advantages the motor chosen is PMSM (Permanent magnet synchronous motor) for the variable speed modern drive which is most widely used in EV’s (Electric vehicle and in Hybrid electric vehicle). Without weakening the field by controlling the DC-link voltage the PMSM machine can run at high speed by implementing ZSI to the drive system. Z source inverter working principle and modulation method is discussed in this study. By considering the Limitation of Maximum voltage and available line current a new Vector control scheme is developed for PMSM drive voltage boosting. At last the proposed system implementation effectiveness and reliability is tested by several simulation and experimental results.
