Abstract

A new converter topology for switched reluctance drives (SRD) is presented. Compared to conventional converter circuits it offers major degrees of freedom leading to a significant performance enhancement of the drive system. An additional switched capacitor per motor phase results in an extended control flexibility. This results in significant improvements of maximum torque, efficiency or torque ripple up to maximum speed. Furthermore a second energy source (e.g. supercapacitors) can easily be integrated in the drive system. Because additional chokes are not required, this leads to compact and attractive drive systems for a wide range of applications.
