This paper is to present the investigation of neural-network-based controller of space vector modulation (ANN-SVPWM) for four switch three phase inverter (FSTPI) fed induction motor drive. This ANN-SVPWM controller completely covers the under modulation and over modulation modes with operation extended linearly and smoothly up to square wave (six-step). The ANN controller uses the individual training strategy with the fixed weight and supervised models. Furthermore, ANN diagnosis method for real-time fault detection of power switches is proposed in this paper. The complete ANN-SVPWM and diagnostic controller can be used in power applications such as motor drives. 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) .
