摘　　要：为给电力变换系列课程提供与现有技术同步的实验内容,开发了无线功率传输综合实验。叙述了无线功率传输装置的结构,根据无线功率传输过程中功率流的调理顺序,依次设计了发送端逆变电路、发送与接收线圈及其谐振网络、接收侧整流器和负载匹配变换器,数字信号控制器通过数字补偿网络进行装置的无线功率传输控制。该实验装置的设计模块化易维护,经实验验证,可以稳定地将15-25V的低压直流输入经过33-77mm的气隙传递至接收侧的48V蓄电池中,传输功率在150-250W范围内连续可调,可适用于本科高年级及研究生的电力变换类课程实验。In order to provide the hand-on experience in the state-of-the-art power conversion technologies courses, the wireless power transfer technology （WPT） is developed. Considering the users ＇ experience and feasibility for experimental teaching, the system hardware structure is evaluated carefully for the WPT teaching device. Following the power flow path, each power conversion stage is designed and implemented, including the sending-end inverter, the sending/receiving coil and their resonant network, the receiving-end rectifier, and the load matching converter. The digital signal controller is used to provide the wireless power flow control using the digital compensation network. The experimental device is modularized and its maintenance is friendly. The test results indicate that the experimental device is capable of transferring the continuously adjustable power of 150W-250W through a 33mm-77mm air-gap reliably, giving the input source of 15-25VDC and 48V battery as the load.
