5-phase Multilevel Inverter for EV Application

The aim of this paper is to reduce the THD in a 5-phase multilevel neutral point clamped inverter and to improve the performance of the 5-phase induction motor used in EV applications. Voltage control of this 5-phase multilevel inverter is done using three different multicarrier PWM techniques (PD, POD, APOD). Simulation analysis is performed using Simulink with R, RL loads connected to the multilevel inverter and obtain load voltage, current waveforms, and THD analysis. This paper implements a better technique for electric vehicle control using a 5-phase induction motor drive with a multilevel inverter system and performance analysis of speed, torque, and stator currents using Matlab-simulink software. The results show that the PD modulation technique provides the lowest THD performance for the system and the motor attains a fast steady state.
