Fault detection using ann for four switch three phase inverter fed induction motor drive

Abstract

This paper is to present the technique for fault detection for Four-Switch Three-Phase Inverter fed induction motor drive. The proposed method requires only motor currents and DC-link current to be measured for detecting and identifying the power switch in which the open circuit fault or short circuit fault has occurred. Furthermore, a diagnosis controller using ANN for real-time fault detection of power switches is suggested. A computer simulation program is developed using Matlab/Simulink together with the Neural Network Toolbox for training the ANN-controller. This method has been validated experimentally using kit ACE 1104 (DSPACE). ©2008 IEEE.
