Implementation of Space Vector Modulated Single-phase to Three-phase Indirect Matrix Converter for Induction Motor Drive Control

Abstract

ABSTRACT This paper presents a space vector modulated single-phase to three-phase (1 × 3) Indirect Matrix Converter (IMC). The IMC is comprised of a front-end side rectifier followed by a voltage source inverter (VSI). DC voltage appears at the intermediate of the rectifier and VSI, this virtual DC-link does not have any energy storage element (battery or capacitor), which reduces total power to weight ratio of the IMC converter, as compared to conventional AC–DC-AC converters. LC-filter is connected at the source side to reduce the harmonics present in the supply side. But the source side LC-filter disturbs the unity power factor (UPF) operation of matrix converter. In this paper, a control technique is proposed to transform single-phase quantities into stationary reference frame in order to maintain UPF at the input stage of IMC. The feasibility of control strategy for the IMC is analyzed in MATLAB/Simulink environment and a laboratory prototype is also developed supplying power to a three-phase induction motor.
