A controller for use in a switched reluctance (SR) motor drive is provided. The controller includes a DC—DC converter coupled to an inverter. The DC—DC converter can be a buck converter, a boost converter, or a buck-boost converter. The control parameters to the DC—DC converter can be optimal. In addition, the bus voltage of the motor drive can be reduced to a level such that the motor operates in single pulse mode. A capacitor can be connected in parallel across the outputs of the DC—DC converter supplying the inverter. Using the DC—DC converter to indirectly profile the phase current can reduce motor torque ripple.
