Fault detection using ANN for four switch Three Phase Inverter fed induction motor drive

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).
