The Switched Reluctance Motor has inherent mechanical strength without rotor winding and permanent magnet. To improve the power factor correction and to perform the commutation faster, several topologies are analyzed such as buck, boost and buck boost, dc-dc converter. This paper presents the boost converter with PFC to improve the performance of the converter with high rectified output. The proposed converter performs the phase current commutation faster. This paper also presents new controller design for Switched Reluctance Motor. The PI controller is used to track the required line current. The simulation of the SRM along with the Asymmetric Bridge converter and proposed converters are performed by the MATLAB software. The results are analyzed and compared, which shows that the new converter performs the phase current commutation faster than the Asymmetric Bridge converter.
