Direct Torque Control of Matrix Converter Fed Five Phase Interior Permanent Magnet Synchronous Motor Based on Space Vector Modulation

Abstract

Matrix Converters (MC) have many advantages over conventional inverters such as sinusoidal input and output waveforms, operation with close to unity input power factor and more compact size. Direct Torque Control (DTC) is known as one of the popular methods in controlling AC drives. This paper presents Indirect Space Vector Modulation (ISVM) model for a three to five -phase MC. Then, DTC is proposed for a five-phase Interior Permanent Magnet Synchronous Motor (IPMSM), fed by a three to five -phase MC. The simulation results of the proposed drive system show very low flux and torque ripples, sinusoidal input and output currents, constant switching frequency and operation with close to unity input power factor .
