提出了一种基于E2类DC-DC变换器的感应耦合无线电能传输系统沿着设计方法。所提出的WPT系统可以在高频下实现高功率转换效率，因为它在逆变器和整流器上都满足E类零电压开关和零导数电压开关条件。通过使用E类逆变器作为发射器和E类整流器作为接收器，在所设计的WPT系统中可以实现高功率传输效率。通过使用在以前的工作中提出的数值设计程序，它是可能的设计WPT系统，而不考虑满足E类ZVS/ZDS条件的阻抗匹配。设计实例的实验结果表明，在100 W的输出功率和200 kHz的工作频率下，总效率为85.1%。
This paper proposes an inductive coupled wireless power transfer (WPT) system with class-E2 dc-dc converter along with its design procedure. The proposed WPT system can achieve high power-conversion efficiency at high frequencies because it satisfies the class-E zero-voltage switching and zero-derivative-voltage switching conditions on both the inverter and the rectifier. By using the class-E inverter as a transmitter and the class-E rectifier as a receiver, high power-delivery efficiency can be achieved in the designed WPT system. By using a numerical design procedure proposed in the previous work, it is possible to design the WPT system without considering the impedance matching for satisfying the class-E ZVS/ZDS conditions. The experimental results of the design example showed the overall efficiency of 85.1 % at 100 W output power and 200 kHz operating frequency.
