| 摘 要： | 介绍了非接触式旋转高频链变压器(Contactless Rotary high Frequency Link Transformer,简称CRFT)在旋转机构电源上的应用,CRFT的使用代替了传统的电能传递方式,即电刷电能传递方式,大大延长了旋转机构电源系统的使用寿命和使用可靠性.采用软开关技术,减少了电能在磁场中传递而进行变换产生的电磁干扰,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,CRFT完全可以在旋转机构供电场合代替电刷及滑环.

| Abstract: | A detailed introduction of the application of contactless rotary high frequency link transformer in the rotary mechanism 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 are achieved.The resonant technique is in-cluded 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 test... |
