Abstract

This paper presents a diagnosis method for the detection and location of open-short switch faults in the three-phase power conditioning system. A method for switch fault diagnosis on the power conditioning system is proposed, based on the concordia transform. The switch fault types and locations on power conditioning system are diagnosed by a method in which analyze the d-q current vector locus and current pattern. The Simulation results confirm the proposed diagnostic method.
