Switched reluctance generator controls for optimal power generation with current regulation

The paper presents a novel method of controlling switched reluctance generators (SRGs) for maximum efficiency with active current regulation. The effect of varying the input control parameters on the efficiency of the SRG is first analyzed through exhaustive data collection through simulation and experiments. The analysis of the collected data showed that the input control parameters that minimize the dc-link current ripple simultaneously also maximize the generating efficiency. A novel control strategy based on the analysis is then developed to maximize the efficiency indirectly through the control parameters that minimize the dc-link current ripple in real time while delivering the commanded generation power. The controller algorithm has been implemented with a 1kW experimental three-phase SRG drive system charging a NiMH battery pack.
