In this paper, two kinds of torque ripple optimization methods are proposed for Switched Reluctance Motors due to the mutual coupling between phases. When phase number of SRM is more than two, SRM is often running in status of two phases excited simultaneously, then mutual inductance will be occurred between phases. The mutual coupling will affect the current waveform, thereby affecting the torque...
The converter of six-phase switched reluctance motor (SRM) requires both less switch devices and independence between phases. So instead of the frequently-used asymmetric half-bridge converter, N+2 power converter is employed in this paper. In N+2 power converter, SRM works in voltage chopping mode. While under common fixed duty-cycle PWM (FDPWM) voltage control, the torque ripple is high and the...
