【摘要】：功率放大器是磁耦合无线电能传输系统的前端功率输入设备,对于无线电能传输系统的高效稳定运行起到至关重要的作用.本文给出了功率放大器的基本拓扑、匹配网络和整体电路设计方法,使其达到较高的传输效率.采用ADS软件对功率放大器性能进行分析,结果表明,设计的功率放大器在8.5 MHz中心频率上,当输入信号为29 d Bm时能够获得的最大功率为18.928 W,效率为89.516%.
[Abstract]:Power amplifier is the front-end power input equipment of magnetic coupled radio energy transmission system, which plays an important role in the efficient and stable operation of radio energy transmission system. In this paper, the basic topology, matching network and overall circuit design method of power amplifier are presented to achieve high transmission efficiency. The ADS software is used to analyze the performance of the power amplifier. The results show that the maximum power of the designed power amplifier is 18.928 W and the efficiency is 89.516 W when the input signal is 29 d Bm at the 8.5 MHz center frequency.
