Abstract

In this paper a detection and fault diagnosis for a Voltage Source Inverter is presented. The need to insure a continuous and safety operation for voltage source inverter involves the need for reliable fault diagnosis techniques. The proposed approach uses an automatic three step algorithm. Firstly, the inverter output currents are measured which will give typical patterns that can be used to identify the fault. Secondly, the Eigenvectors/Eigenvalues of the 3D current referential are computed. Finally the proposed algorithm will discern if there is any fault and report the faulty switch. The proposed approach was experimentally implemented and its performance verified on various types of working conditions.
