A novel dual-output six-switch three-phase inverter

Abstract

A novel dual-output six-switch inverter topology is proposed in this paper for independently supplying two three-phase loads. This inverter employs less number of semiconductor devices compared to former dual-output inverters proposed so far in the literature. Reducing the number of switches and hence drive and control circuits results in reduction in total cost and loss and increases the system efficiency and reliability. The new configuration is introduced and carrier-based PWM schemes for its two defined modes of operation (constant frequency and variable frequency modes) are developed for it. Furthermore, analysis of semiconductor loss is performed and the results are compared with counterpart topologies. Simulation and experimental results will be presented to demonstrate the theoretical knowledge.
