摘要
开关磁阻电机(SRM)具有坚固耐用、功率密度高、调速范围广、起动转矩大等一系列优点,然而关于其功率变换器的研究较少。结合国内外文献,分析不对称半桥功率变换器、公共开关型功率变换器、裂相型功率变换器以及三开关型功率变换器等传统功率变换器的结构特点;对比了传统变换器的优缺点,在此基础上分析了几类新型功率变换器拓扑结构以及电流电压转换关系,并概述了功率变换器未来发展趋势,为功率变换器发展提供参考。
Switched reluctance motor(SRM)has the advantages of ruggedness,high power density,wide speed range,large starting torque and so on.However,there are few researches of power converter for SRM.On the basis of domestic and foreign literature,the asymmetric half-bridge power converter,common switching power converter,split-phase power converter,and three-switch power converter are analyzed.The advantages and disadvantages of these traditional converters are compared.After that,the topology of several new types of power converter and their current-voltage relationship are analyzed,and the future development trend of SRM power converters is summarized.This research will provide reference for the future development of power converters.
