Pulse Width Modulation Technique for Multilevel Operation of Five-Phase Dual Voltage Source Inverters

Received: 24 December 2020 Accepted: 18 March 2021 To supply five-phase variable speed drives, five-phase voltage source inverters are used. Some of the applications of five-phase variable speed drives are traction, electric & hybridelectric vehicles, and ship propulsion. Different control systems are available for the controlled output of the five-phase VSI, but space vector pulse width modulation is popular because of its simpler digital implementation. In this paper, the SVPWM schemes have proposed and analyzed for the multilevel operation of a five-phase dual voltage source inverter. The proposed techniques do not contribute a voltage balancing issues such as in multilevel neutral point clamped (NPC) inverters. The author analyzed the performance of five-phase VSI based on THD and fundamental components. Matlab/Simulink model has provided for results verification.
