To achieve the precision control of phase current or phase flux linkage in switched reluctance motor (SRM), the higher switching frequency of converter is required to increase dynamic response speed. However, higher switching frequency may cause higher switching losses, higher Electro-Magnetic Interference (EMI) and lower overall efficiency. The use of soft-switching techniques in converter can resolve these issues. A brand new soft-switching converter for SRM is presented, which has advantages… 

To achieve the precision control of phase current or phase flux linkage in switched reluctance motor (SRM), the higher switching frequency of converter is required to increase dynamic response speed. However, higher switching frequency may cause higher switching losses, higher Electro-Magnetic Interference (EMI) and lower overall efficiency. The use of soft-switching techniques in converter can resolve these issues. A brand new soft-switching converter for SRM is presented, which has advantages of all Resonant Switch converter (RS), Resonant dc Link converter (RDCL) and Pulse Width Modulation (PWM). The addition of external commutating devices to conventional asymmetric bridge converter for SRM achieves the soft- switching of power devices. The conditions of soft switching are deduced and a practical design consideration is given. Finally, detailed simulation study of the complete system is presented and is validated with experimental results.
