SVM TECHNIQUE APPLIED TO DC-LINK THREE -PHASE THREE LEG AC/AC CONVERTER USING NINE IGBT

Abstract

This paper presents the implementation of a novel three phase three leg AC/AC converter. The converter employs only nine switches and has the capability of delivering sinusoidal input and outputs with unity power factor. In this paper, a new three-phase to three-phase converter for ac motor drives is presented. The converter provides both an input rectifier and an output inverter by sharing a leg in order to reduce the number of power switches. The features of such a converter are compared to those of the back-to-back two-level voltage source converter and matrix converter.
