Performance of Switched Reluctance Motor Driven by Novel C-Dump Inverter

Novel C-Dump 인버터에 의한 SRM의 구동특성

This study describes the influence of the mutual inductance between the adjacent phase windings of variable reluctance motor[VRM] and presents a new type of inverter for reduction of such influence. In this inverter topology, though an additional power switch is used as compared with the conventional C-dump inverter circuit, unwanted negative torque produced by the mutual inductance is remarkably reduced. Hence, the circuits results in increase of the average torque and contributes to the improvement of overall drive efficiency. Theoretical prediction is verified by experimental results obtained with the integration of presented inverter and prototype 6/4 VRM.
