Dynamic Characteristics of Rotating-Rectifier Brushless Excitation Circuit

对旋转整流器式无刷励磁电路的动态特性进行了较深入的计算机数字仿真分析。比较了三相桥式整流和三相零式整流两种励磁电路的动态响应特性，得出换相电抗负载因素、励磁机和主发电机励磁绕组时间常数对动态响应时间的影响关系。这些关系的揭示对合理设计旋转整流器式无刷发电机参数，提高整体系统性能具有一定的指导意义。

The dynamic characteristics of a rotating-rectifier brushless excitation circuit are simulated on a digital computer and analysed deeply. The dynamic characteristics of full-wave-rectifier and half-wave-rectifier excitation circuits are also compared. The effects of the commutating reactance-load factor and the time constants of excitation windings of exciters and main generators on the dynamic response are shown in the paper, all of these results are helpful to the resonable design of exciters and main generators for improving the performance of the whole electrical control system.
