摘　　要：介绍了非接触式旋转高频链变压器在卫星电源上的应用,使用非接触式旋转高频链变压器代替了电能传统的传递方式——电刷,大大延长了卫星电源系统的使用寿命和使用可靠性。并采用软开关技术减少了电能为在磁场中传递而进行变换产生的电磁干扰,创造性地解决了与静止供电完全没有物理接触的旋转电路的供电问题。实验证明,非接触式旋转高频链变压器完全可以在旋转机构供电场合代替电刷及滑环。A detailed introduction of the application of contactless rotary high frequency link transformer in the satellite power supply is given. To use the contactless rotary high frequency link transformer instead of carbon brushes which is traditionally and widely used, a longer life-span and higher reliability is achieved. The resonant technique is included in order to eliminating the EMI due to power conversion, and the power supply to the rotary circuits is realized by a creative method. The practical tests demonstrates its superiority towards carbon brushes and slip rings.
