摘　　要：高频功率源作为电场耦合式无线电能传输系统的重要组成部分,其工作效率关系着整个系统的效率。针对传统高频逆变拓扑电路体积过大、设计复杂和逆变损耗高等问题,根据无线电能传输系统对所需电能的要求,设计了高频高效的E类功率放大器作为其前端的高频功率源。运用电路理论和ADS射频仿真软件对E类功放电路进行理论和仿真设计,并在此基础上制作实验样机。实验测试表明,所设计的E类功率放大器具有较高的电能转换效率,且电路体积小,工作稳定。A high-frequency power source is an important part of the electrical-field coupled wireless power transfer (WPT) system, and its operating efficiency plays an essential role for the whole system. Considering that the traditional high-frequency inverter topology circuits have problems such as overlarge volume, complex design, and high inverter loss, a high-frequency high-efficiency class-E power amplifier was designed as the front-end high-frequency power source according to the requirements of the WPT system for power quality. Theoretical and simulation designs for the class-E power amplifier circuit were carried out by the circuit theory and ADS radio frequency simulation software, based on which an experimental prototype was fabricated. Experimental results show that the developed class-E power amplifier had advantages of high electricity conversion efficiency, small size, and excellent stability.
