摘　　要：针对在无线电能传输分析中多以磁耦合谐振技术为主,缺少对电谐振耦合机理的分析这一问题,文中根据对称性原理,提出无线电能传输机理中应该包含磁谐振耦合和电谐振耦合两种谐振耦合机理,并从电路的对偶性角度出发,给出了电谐振耦合电路模型并推导出传输功率增益的理论公式。通过对电路参数的分析得出了传输功率增益的变化规律,为无线电能传输系统的设计提供了参考。The core of the current wireless power transmission technology is based on the magnetic coupling res- onance mechanism. According to the principle of symmetry, the mechanism of the wireless power transmission should include two kinds of resonant coupling mechanism of the magnetic and the electric resonance coupling. In this paper, the theoretical formula of the electric resonant coupling circuit model is presented and the theoretical formula of the transmission power gain is derived from the dual nature of the circuit. Through the analysis of the circuit parameters, the variation of the transmission power gain is obtained which has a guiding significance.
