UPF 및 정현파 입력 특성을 가지는 새로운 SRM 구동용 converter

A Choppingless Converter for an SRM with UPF and Sinusoidal Input Current

This paper proposes a new converter for switched reluctance motors using a Boost converter in conjunction with a Buck converter. The proposed converter has a unity power factor(hereafter referred to an UPF) in the ac input regardless of the load variations. Moreover, compared to the conventional converter topologies, the total system efficiency is improved by introducing choppingless voltage control methods in the machine side converter and an energy recovery snubber in the pre-voltage regulation stage, respectively.
