Abstract
In this paper the novel converter topology for the switched reluctance motor drive is proposed which is composed of the minimum switch per phase and is supplied by ac voltage source while the conventional SRM converters are supplied by dc voltage source. The single phase voltage source inverter is used to obtain the ac voltage source. This proposed converter could return the energy stored in the phase coils after turning off the phase switch. A buck boost converter is added to the topology for controlling the amount of energy recycling to the source. This enables the improvement of average torque in SRM. The motor torque is controlled by adjustment of the current of the inverter. Also the relative position angle between stator and rotor can be controlled with the same converter. Simulation for novel SRM power converter connected to the voltage source inverter is carried out using PSIM 6.0. The torque output of the proposed converter has been compared with the torque output of the conventional SRM power converter.
