The converter structure and control strategy were researched in response to the problems of switched reluctance motor (SRM) based on the linear model of SRM. The magnetic characteristic carve was got after analyzing the system structure of SRM, the inductance carve and the equivalent circuit of heat transfer domain and post under the ideal conditions of SRM ran entirely in linear flux region. The control parameters of SRM, power converter structure and the method of commutation were discussed and the Matlab simulation of some parameters was finished. The simulation results show that the simulation is consistent with the theoretical analysis on the condition of θon=0°, θoff=30°and without load, so this provides a theoretical support for switched rReluctance drive (SRD) application in engineering practice.
