Abstract

A new three-phase voltage source ac-ac converter is proposed, also known as a three-phase dual-buck ac-ac converter. It needs less shoot-through limiting inductors to decrease the cost and improve the power density. It has step down operation. The suggested converter has high immunity against the shoot-through of voltage sources or capacitors and can eliminate the dead-time between the switching signals. Thus a system with improved reliability can be designed with the proposed converter. MOSFET can be used as switching devices in the proposed converter without the need of reverse recovery worries of body diode, due to the bad reverse recovery of MOSFET body diodes, and advantages of MOSFETs such as low switching loss, resistive conduction voltage drop, and fast switching can be obtained. As a result, the size of passive components can be reduced by using a high switching frequency.
