摘　　要：针对晶闸管相控整流式同步电动机励磁装置的问题,提出了一种新型的同步电动机励磁电源。对新型励磁电源所用的高频变压器的设计和控制进行了详细阐述,着重从高频变压器的磁芯材料选择,频率确定,绕组计算,软启动策略和以C8051F020为主控制器的电源启动和控制方案,实验证明,新型励磁电源的重量体积小、损耗低。This paper introduces a high- frequency transformer used in a new exciter for the synchronous motor. The choice of magnetic core, the design of the winding, the soft-starting and the strategy of control based on C8051F020 are described in detail. Comparing with the old type of exciter, the new one has many advantages and can easily be used.
