Design of a novel high grade converter for switched reluctance motor drive using component sharing

Switched reluctance motor (SRM) has become an important alternative in various applications. When SRM is operated as generator (SRG), it´s widely used in aeronautical industries and primely as wind generator in wind based energy generating system. In this paper various converter topologies of the switched reluctance motor drive has been studied. A comparison between the various converter topologies has been done on the basis of Phase current waveform, fourier analysis and total harmonic distortion. The simulation of various converter topologies of switched reluctance motor drive has been done using P-SPICE. A new and cost effective converter, for switched reluctance motor drives is proposed. The new method uses component sharing, thus it significantly reduces half of the component cost. This component sharing converter topology is a modification of the conventional asymmetric bridge converter for switched reluctance motor drives. The requirements of switched reluctance motor drives on converters and the operation of the component sharing converter are analyzed using Matlab/Simulink. Furthermore, the simulation results confirm the feasibility of the proposed converter.
