hope this helps..
Dear Jenifer Amla ,
In switched reluctance motors, the motor torque is proportional to the square of the current so that the converter has to supply only unidirectional currents. Therefore, converters feeding the SRM are of the unipolar type, and they generally use one switch per phase. The function of the converter is to switch the current from one phase to another in synchronism with the rotor position so as to provide positive current in the phases with increasing inductance.
Also, the choice of converter topology depends heavily on your application. If you want to control the machine in current, torque or speed, I recommend you to use an asymmetric half-bridge converter that uses only one switch per phase but also for the simplicity of powring the SRM-phases independently that its offered, thus its robustness.
I suggest you take a look at this paper:

I agree that Asymmetric Half-Bridge (AHB) is the more common topology.
Nonetheless, you may take a look at the following paper for a newer review:
