The structure and principle of the T-type 3-level reverse voltage source that will be fed to three-phase induction motors will be presented in this study. The implementation of Space Vector Pulse Width Modulation (SVPWM) and the math models of the induction motor, the stator currents, and the speed controller design of the electric traction drive system based on Field-Oriented Control (FOC) will be also shown. This three-level T-type inverter in the FOC structure decreases Total Harmonic Distortion (THD) more than the previous two-level inverters. By combining the FOC control structure with the T-type 3-level inverter, the speed and torque responses necessary for railway traction motor load were improved. Finally, Matlab/Simulink will be used to demonstrate the correctness of the T-Type multi-level inverter theory.

This paper presents the drive control of a Permanent Magnet Synchronous Motor (PMSM) fed by a multi-level inverter for electric vehicle application. In particular, the advantage of torque mobilization of the PMSM engine has been selected for the electric drive of electric cars. In addition, to improve the transmission quality of electric vehicles to ensure requirements, the T-type three-level inverter will be proposed in the control structure of electric vehicles. Moreover, the challenge of torque entails determining the appropriate physical qualities. Therefore, the design of an active damping and current controller to provide rapid and precise torque response to the induced torsional moment was also conducted. Finally, the results of Plecs simulations prove the correctness of the theoretical research. The simulation results demonstrate the research theory.
