In many industrial applications Switched Reluctance Motor (SRM) is mainly used because of its high efficiency and low maintenance. Its mechanical structure is so simple to construct because it has salient poles, stator and rotor. Stator has concentrated winding and there is no winding on rotor. So therefore no need of commutator and brushes. The SRM drive has another advantage of fast dynamic response and fault tolerant capability. However since this drive requires DC excitation so we need to convert AC-DC, this ACDC conversion imposes low power factor on grid side and this leads to high losses. Here we have consider air-compressor used for household applications. In this paper we are proposing PWM rectifier on AC side for Power factor correction the same rectifier is used for control of DC-link voltage. Also SRM motor is Driven by Asymmetrical converter, the speed of the Motor is changed by changing the DC-link voltage of Asymmetrical converter. A MATLAB/SIMULINK based model is developed for various loading conditions and simulation results are presented.
