Improved Phase-Clamping PWM Techniques with Space Vector Approach for Five-Phase System

The most of the researchers are increasingly their favor of the adoption of electric vehicles to mitigate the environmental threats posed by the widespread use of fossil fuel-powered vehicles. Multi-phase drive systems offer distinct advantages for electric vehicles due to their superior power density. Effectively implementing pulse width modulation (PWM) is essential for driving multi-phase drives. This paper focuses on the five-phase voltage source inverter and explores various modulation techniques within a space vector-based approach. The paper introduces a novel switching sequence designed to enhance phase-clamping PWM techniques, incorporating different clamping durations. This improved phase-clamped PWM (IPCPWM) technique demonstrates superior performance in terms of harmonic spectrum and current ripple reduction. Furthermore, the study evaluates the switching energy loss associated with these techniques. The proposed PWM techniques is simulated and analyzed the results.
