A six-switch three-level current source inverter

Abstract

In several applications DC/AC converters are widely used; traditionally they can be classified in voltage source inverters (VSI) and current source inverters (CSI). Their use depends on the application. Other possibility for the DC/AC conversion is the multilevel configuration, and the most analyzed is the VSI. In this paper a multilevel current source inverter (MCSI) is proposed. The operation, analysis and implementation are presented; also simulation and experimental results are shown.
