SRM의 병렬권선 운전 특성

Characteristics of Parallel Winding Drive of SRM

In a motor drive, the current rating is directly related to the rating of a switching device, and the parallel switching operation for a cost reduction is the alternatives because it has the smaller current rating through current division. There are many investigations for the parallel switching operations to equaling the current division. However it remains many problems for practical usage. This paper proposes a new parallel operation which uses a parallel phase winding to remove the traditional effect of switching device such as saturation voltage according to the division of current. The proposed strategy is verified by theoretical and experimental verification.
