Control of the SRM operating as a motor/generator

This paper deals with switched reluctance machine used as a motor/generator drive. The motoring operation is achieved with a half-bridge converter. A strategic modification in the electronic converter topology is required to allow the generator operation mode. It is achieved automatically as well as the phase switching angles control is simultaneously provided. Three different techniques to control the voltage delivered to the load when the machine is operating as a generator are evaluated. All of them exert control on the machine magnetization level. Simulated results are included to show the feasibility of the proposed techniques and to confirm the applicability of the switched reluctance machine as a motor/generator device.
