针对在 13.56 MHz、27.12 MHz 和 40.68 MHz 频段运行的无线电源应用，对 E 类逆变器和同步整流器设计进行了比较研究。所有设计都使用相同的 GaN 开关、栅极驱动器和 PCB 布局，为比较不同设计的性能提供一致的参考。利用时间反转对偶性理论将同步整流电路设计为逆变器的电路对偶。对不同频段以及逆变器和整流器的功率效率进行了比较。结果表明，逆变器和整流器在效率方面匹配良好。
A comparative study of class-E inverter and synchronous rectifier designs is made for wireless power applications operating in the 13.56 MHz, 27.12 MHz and 40.68 MHz frequency bands. All the designs use the same GaN switch, gate driver, and PCB layout to provide a consistent reference for comparing the performance of the different designs. The synchronous rectifier circuits are designed as circuit duals of the inverters using the theory of time reversal duality. A comparison of power efficiency is made for different frequency bands as well as for the inverter and rectifier duals. The results show that the inverter and rectifier duals are well matched in terms of efficiency.
