Development of an improved switched reluctance motor drive using a soft-switching converter

摘要

The use of soft-switching power converters in association with switched reluctance motors (SRM) potentially allows the fabrication of motor drives with increased power density and with better efficiency than other types of drive system. Additionally, the SRM can be operated with high reliability at very high speeds in harsh environments. As a result, a soft-switched SRM drive system can compete favourably with other drive types, in applications where compactness and robustness are required. In this work, the feasibility of a soft-switched reluctance drive is evaluated using simulations and validated with experimental results.
