Abstract

In a three phased switched reluctance drive, the input DC voltage source is universally supplied by a circuit comprising of a diode bridge rectifier model and a capacitive filter interfaced to an AC line. The diode bridge rectifier absorbs distorted current from the AC line, which evolves the degraded power factor (PF) and system efficiency is very low. A three phased 6/4 SRM drive system is highlighted in this paper, which comprise the recognition of a drive circuit for the minimization of torque ripples and power factor enhancement with a decisive asymmetric switching topology. A unique switching topology for SR drive is confined by a closed loop control procedure. The validity of the proposed switching scheme is controlled by PI control design to attain favorable advantages, dynamically analyzed by Matlab/Simulink environment tool, the results are conferred.
