New ZCS resonant power converter topologies for variable reluctance machine drives

Abstract

Zero current switching (ZCS) converter topologies for variable reluctance machine drives are described. ZCS makes high frequency operation possible while maintaining low switching loss and reduced levels of electromagnetic interference (EMI). This increase in frequency translates directly into improved current regulation in the machine phases, resulting in a high performance drive. The machine fundamentals are reviewed, converter topologies are introduced, and simulation results of the total drive are presented.<>
