摘要
直流母线电压对永磁同步电机控制系统中整流器及逆变器的容量和成本,永磁同步电动机的设计及控制性能等有重要的影响,是电机设计及控制需要考虑的一个重要参数。文章分析了直流母线电压对调速永磁同步电动机的作用及对电机设计和整个控制系统的影响,通过分析所得的结论对电机本体及控制系统设计时母线电压的选取具有一定的参考价值。
DC bus voltage is an important parameter to design and control of permanent magnet synchronous motor（PMSM）,which has great impacts on capacities and costs of rectifier and inverter and on the design and control performances of PMSM.The paper makes an analysis on DC bus voltage＇s function in variable-speed PMSM and its effects on the design of motor and the control system.The final conclusions can be well referenced by the selection of DC bus voltage in the design of motor and the control system.
