A 3Ф-3Ф quasi Z-source matrix converter for residential wind energy systems

Abstract

When compared to the Z-source inverter, the quasi Z-source inverter offers several advantages, including lower component ratings, reduced source stress and switch count, and simpler control strategies. In this study, the concept of a quasi Z-source network is extended on a 3Φ-3Φ indirect matrix converter. The converter, destined for residential wind energy systems, is based on the ultra-sparse matrix topology characterized by the minimum number of semiconductor switches. The quasi Z-source network is placed between the three-switch input rectifier stage and the output six-switch inverter stage.
