Integrated converters for switched reluctance motor drives

Switched reluctance motors (SRM) are relatively inexpensive and robust. The proportional cost of the power electronics is large especially for lower power drives. It is therefore important to optimize the power converter for the practical applications. This paper presents the concept of integrated converters for SRM drives. Basic converters based on the sub-integrated concept are also discussed for the purpose of power factor correction in SRM drives. In addition, basic converters for DC-SRM drives are proposed. Finally, according to the integrated converter concept, three integrated converters based on the variable DC link voltage for SRM drives are introduced.
