Study of power factor in SRM drives under current hysteresis chopping control

Based on the simulation and experimental analyses, this paper investigates the effects of the control parameters and outputs upon the power factor in switched reluctance motor (SRM) drives under the current hysteresis chopping control. The control parameters include the reference current, hysteresis band, turn-on angle, turn-off angle and input AC voltage. The outputs consist of the speed and average torque. The relations between the power factor and the above variables are shown. The conclusions given in this paper are used conveniently by fellow researchers as a useful tool to design SRM drive controllers that operate with good power factor.
