摘　　要：接触式旋转电子设备具有易磨损、无电气隔离等缺点,不利于设备的安全可靠。提出了一种非接触式旋转磁耦合无线电能传输(ICPT)装置,由旋转松耦合变压器、S/LCC补偿谐振变换器和DC/DC变换器组成,具有电气隔离性好、灵活性高、安全性好等优点。为了验证分析和设计,制作了一个400 W的可旋转50 mm间隙的样机,并进行了测试,结果表明从直流40 V输入到直流40 V输出的总效率为84.3%。Contact-type rotary electronic devices have the disadvantages of easy wear and no electrical isolation,which is not conducive to the safety and reliability of the device.In this paper,a contactless rotary inductively coupled power transfer(ICPT)device is proposed,which consists of a rotary loosely coupled transformer,S/LCC compensated resonant converter and DC/DC converter.The ICPT device provides electrical isolation,higher flexibility and greater security.In order to verify the analysis and design,a 400 W rotatable prototype with a 50 mm gap is fabricated and tested.An overall efficiency 84.3%is achieved from DC 40V input to DC 40 V output.
