Nine-Switch Current-Source Inverter-Fed Asymmetrical Six-Phase Machines Based on Vector Space Decomposition

This paper proposes to employ a nine-switch converter as a current-source inverter (CSI) to supply asymmetrical six-phase motors. To achieve a compact high-density power electronic converter, the nine-switch converter has attracted the attention of researchers as a reduced-switch count DC/AC converter for six-phase motors. This configuration not only reduces the number of power semiconductors but also removes bulky dc-link capacitor. In order …
