The paper proposes a new control strategy of the energy recovery chopper in a capacitor-dump (C-dump) switched reluctance motor (SRM) drive. The proposed strategy is based on the sliding mode control theory and allows a continuous output current operation of the chopper to be attained with low semiconductor current peaks and low capacitor voltage fluctuations. In the first part of the paper, the dynamic equations of the chopper are formulated from the point of view of the capacitor voltage control. The equations show that the chopper operates as a boost dc-to-dc converter in a regenerative mode. The sliding mode control is then designed, and the effects of the converter and the control parameters on the chopper performance are pointed out. Experimental results are presented and discussed in the last part of the paper.
