A new hybrid asymmetric and buck-boost fronted converter for SRM with active boost voltage capability

Abstract

In order to improve performance of switched reluctance motor (SRM) at high speed, a new hybrid asymmetric and buck-boost fronted converter for SRM with active boost voltage capability is proposed. Different from existing converters with boosting voltage, the proposed converter has an active regulation ability of boosting voltage, in which voltage level is independent from switching and dwell angels. Firstly, the basic structure and operating modes are introduced and analyzed. Secondly, the key parameter such as inductor and boosting capacitor is investigated and designed. Finally, some experiments are implemented and results show the validation of proposed method.
