摘要 开关磁阻电机调速系统通过特定的功率变换器来完成各相绕组的开通与关断工作。功率变换器是开关磁阻电机运行时所需能量的供给者,是系统的中枢执行机构。合理选择和设计功率变换器是提高开关磁阻电机调速系统性价比的关键之一。由于经典开关磁阻电机功率变换器需要功率开关器件多,成本高。本文在经典功率变换器的基础上设计了一种含谐振电路的新型开关磁阻电机功率变换器。通过MATLAB仿真,与经典功率变换器进行比较,结果表明本文设计的新型功率变换器有效地提高了开关磁阻电机调速系统的性价比。 The connection and disconnection of each phase winding in SRD is inseparable from a specific power converter.The power converter is the supplier of energy needed to run SRM.It's the system's central executive body.A reasonable selection and design is a key to improving the performance/price ratio of SRD.The power converter of classic SRM requires more switching devices,and the cost is higher.This paper designs a new power converter with a resonant circuit based on the classic power converter. It is compared with classic power converters through MATLAB simulation.The result shows that the new power converter can effectively improve the performance ratio of SRD.
