Abstract

This paper presents a new method of switching management for four quadrant switches (FQS) of matrix converters. By discriminating the FQS command orders, it is possible to lay down the FQS configuration (transistor or diode). The presented method uses the load current sign and zero closeness information to ensure good sequencing of command orders. By using Mealy state machines, we simplify the existing state diagrams for any phase number switching cell. The successful results on a three-phase switching cell, without oversized power circuit, validate this new state diagram structure.
