Symmetrical Space Vector Modulation of Three Phases Indirect Matrix Converter

Abstract

This paper presents the Space Vector Modulation (SVM) of the Indirect Matrix Converter (IMC) topology supplying an inductive load (RL). This converter consists of two stages, a rectifier and an inverter which are connected without dc link capacitors. The rectifier ensures the four quadrants operation. The SVM technique of the indirect matrix converter is aimed to guarantee the control of the semiconductors in good conditions. So, provides balanced output voltages with controllable amplitude and frequency, a maximum value of the ratio between the output and the input voltages and a displacement factor near unity regardless the load. Simulation results using Matlab/Simulink and the performance of the IMC structure are discussed and evaluated.
