Abstract :

This work describes a method in improving the input current total harmonic distortion as well as power factor of a three–phase diode rectifier circuit. In this method, three bidirectional switches are used across the three–phase supply and load to eliminate the lower order harmonics and shunt active harmonic filters is connected at input stage to eliminate the higher order harmonics. The buck regulator connected at the output stage regulates the voltage applied to the DC motor load. The Adaptive Neuro–Fuzzy Inference Systems (ANFIS) is used to generate the triggering pulse for the bidirectional switches. The performances of DC motor drive are evaluated with and without shunt active harmonic filter. The analysis and simulation results of three phase rectifier are also presented in this paper
