This paper offers a new converter for switched reluctance motor (SRM) drive which uses one switch in each phase. One switch for each phase is the least number of switches among the converters used in the switch reluctance motor drive. Also, the proposed converter enjoy from an important characteristic which makes it suitable for high speed drive applications. This is due to the fast phase current commutation capability of this converter. Therefore, the generation of negative torque and consequently, large generated torque ripples in SRM drive are resolved. SRM drive simulation using the proposed converter is presented and the results are compared with the asymmetric converter which is usually used in SRM drives.
