Fault Modeling and Fault Diagnosis of Three-Phase Inverter Circuit

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 287)


As in the non-normal factors, the switches and diodes of electronic power circuits prone to failure, three-phase inverter circuit, for example. In this paper, we make some simulations for the open-circuit of the switches and diodes of three-phase inverter circuit on MATLAB/Simulink platform. Besides, we analyze the fault waveform and extract the feature quantity characterizing the open-circuit fault of switches and diodes. At last, we achieve the accurate detection and location of the fault using normalized dc-component method and make the simulations to verify the above-mentioned theory.
