Abstract
This paper deals with the analysis of switched reluctance motor drives for different drive circuit topologies used in automobile. Therefore, we attempt to improve the weaknesses associated with the asymmetric bridge converter in the limited internal environment of automotive application. Two kinds of c-dump converters are tested in terms of dump capacitor voltage, speed response according to the variation of advance angle and efficiency for the radiator cooling-fan drive of an automobile. They enable more economical and efficient converter topology for automobile industries. This paper describes the performance characteristics of 12 V–250 W–3000 rpm SRM drives for automobiles. Computer simulation and experiment results are then presented to verify the performance of the two kinds of c-dump converters.
