Abstract
Direct Matrix Converter (DMC) solves problems due to the two-stage power conversion mechanism for heavy industrial drive applications. Control of multiphase drives operated by DMC is a serious problem due to the lack of technological advancement. A model predictive direct torque control (MPDTC) scheme for a five-phase induction motor (FPIM) driven by a three-to-five (3×5) phase DMC is therefore proposed in this paper. The proposed MPDTC uses the concept of virtual vectors to eliminate the effect of the xy component on 3×5 DMC output voltage space vectors. By using ranking analysis, the flux and torque of FPIM is controlled along with the grid power factor. The proposed work is simulated and further validated by DMC fed FPIM hardware prototype using FPGA based controller.
