Preliminary Design Results for the Switched Reluctance Cycloconverter

The switched reluctance cycloconverter (SRC) is a power circuit for generating AC with a switched reluctance machine (SRM). It uses a single power electronic conversion step to achieve higher system efficiency compared to alternative approaches. The basic SRC system is described. Design results for a 400Hz, three phase, 60kVA (90kVA for 5 minutes and 120 kVA for 5 seconds) variable speed constant frequency (VSCF) system is presented. The machine and control designs are described. The unique design issues that exist for the SRC compared to a conventional DC SRM system are pointed out. Performance predictions for the final system design are presented.
