Abstract: In this paper, the authors study the effects of the control parameters and outputs of SRM drive systems on power factor through theoretical, simulation and experimental analyses. The control parameters and outputs include turn-on angle, turn-off angle, input voltage, duty cycle of PWM, speed and torque. The analyses are carried out at three operation modes of SRM drives with voltage source, i.e., single-pulse operation, voltage PWM with hard chopping and voltage PWM with soft chopping. This study reveals completely the relationships between power factor and the above parameters. Moreover, the authors propose the new ideas to improve power factor in SRM drives, based on the analysis results. This study is very important for understanding clearly the parameters to affect on power factor, and the conclusions is quite helpful in designing good controller to improve power factor of SRM drive systems.
