Power factor improvement using current source rectifier with battery charging capability in regenerative mode of switched reluctance motor drives

In this paper, a two-stage power converter based on current source rectifier (CSR) is proposed to improve the power factor of Switched Reluctance Motor (SRM) drives and Battery Charging Capability in Regenerative Mode. CSR stage in the input of SRM converter, eliminate dc link's capacitors and create the capability of energy saving in regenerative operation mode of SRM drives. The space-vector modulation (SVM) is used in the CSR switching. The validity and effectiveness of the proposed approach is shown by simulation, also it is verified experimentally by using a laboratory 4-KW SRM setup based on TI TMS320F2812 platform. The results demonstrate a good agreement with the required conditions.
