초록
A novel torque ripple reduction scheme of single-phase SRM with high power factor is presented. The proposed SRM drive has one additional active switches in the conventional asymmetric inverter. In order to get a higher power factor, the source current is controlled sinusoidal, And additional excitation current is added from charge capacitor due to torque ripple reduction. The switching period of source and charged voltage is controlled properly to get unity power factor and torque ripple reduction. The characteristics and validity of the proposed scheme is discussed with some simulation results.
