Issues of matrix converters: Technical review

Abstract

Matrix converter is a powerful AC-AC converter for the application of induction motor drives with sinusoidal input currents and no DC-link capacitor. It offers remarkable advantages over other alternatives in applications requiring improved utility interaction and critical weight/volume reduction. This paper presents a technical review on related issues of induction motor drive fed by matrix converters (MC). The first discussions presented the special difficulties involved in matrix converters. These are partly conceptual, partly concerning circuit topology, and current commutation technique. The second discussion analyzes the control and modulation which are of particular interest. The third discussion describes the hardware development modes studies.
