A SPWM Strategy Based Dual-Inverter Control for Electric Vehicle with Open End Winding Induction Motor

This paper presents a comprehensive study on the implementation of a dual 2 -level (2L) voltage source inverter (VSI) to drive an open-end winding induction motor (OEWIM) for electric vehicle (EV) applications. This paper presents a mathematical model of an OEWIM drive, which is powered by dual 2L VSI with separate DC supplies. A sinusoidal pulse width modulation (SPWM) strategy is employed, incorporating a phase shift of the carrier wave. By comparing a sinusoidal wave with a triangular signal, this strategy enables the generation of swing states for the two inverters in a spontaneous and symmetrical manner. The proposed configuration offers numerous advantages, including improved efficiency, reduced harmonic distortion, enhanced control capabilities, and fault-tolerant operation. The proposed system is designed to meet the demanding requirements of EVs, such as high torque density, fault tolerant operation, and improved power quality. In this study, through the suggested model utilizing the MATLAB/Simulink platform for analysis and simulation. The performance is validated thought experiments. The proposed model benefits from a robust and versatile environment that enables accurate representation and evaluation of the system’s behavior, performance, and dynamics.
