Abstract

For heavy industrial drive applications, the direct matrix converter (DMC) solves the problems caused by the two-stage power conversion mechanism. Due to a lack of technological advancement, the control of multiphase drives operated by DMC is a significant cause of concern. This article thus presents a direct torque control (DTC) scheme based on space vector pulsewidth modulation (SVPWM) for a five-phase induction motor (FPIM) driven by a three-to-five (3\times 5) phase DMC. This proposed SVPWM-DTC employs the virtual vector (VV) concept to eliminate the effect of the xy component on 3\times 5 DMC output voltage space vectors. A novel approach is applied to analyze the effect of SVPWM-VV on the stator flux, torque, and speed of FPIM drive. Additionally, this SVPWM-VV regulates the input power factor of 3\times 5 DMC. The proposed work is simulated first and further validated by 3\times 5 DMC fed FPIM hardware prototype using field programmable gate array (FPGA)-based controller.
