摘　　要：主要研究了一种基于E类功率放大器的非接触感应电能传输拓扑,分析了其运行的基本原理,并主要在感应充电等实际应用场合中充电负载会出现大范围变动的情况,从负载的角度出发,对原、副边补偿阻抗网络的选择和系统各参数的设计,给出了基于最优负载下的具体设计方法。理论和实验结果表明,在负载大范围变动时,无须外加复杂的控制电路,依靠系统本身的阻抗响应即可实现特定的功率传输特性,同时保持较高的传输效率。This paper mainly presents a topology of inductively contactless power transfer based on class-e power amplifier. The analysis of operating principles is given. Found on the situation that the charging load varies in a wide range in some practical applications such as induction charging, this paper starts from the load to choice the primary and secondary compensation networks, and designs various system parameters. Specified design method based optimized load is proposed. The theoretical and experimental results show that, across a wide range variation of load, the system has no need for additional complicated control system but relies on its own impedance response to achieve required power delivery property, meanwhile remaining high transmission efficiency.
