Abstract  

 According to mutual inductance model of inductively coupled energy transfer system (ICETS), a three-factor method was proposed for designing ICETS. In this method, coupling coefficient, primary and secondary selfinductance ratio of separable transformer, and quality factor of energy receiver circuit were  three factors, which were used to design ICETS. Characteristic parameters of the ICETS were expressed as functions of the three factors under resonant state. Based on transfer efficiency of separable transformer and requirement of device stress, the ICETS were designed. Characteristics of four different compensation circuits were analyzed and compared, the circuit with primary series compensation and secondary parallel compensation (SP) was selected, a prototype with output power 100 W was designed. Results show ICETS were layout by the three-factor method, High transfer efficiency of separable transformer and low voltage stress of compensation capacitor are obtained. Experiments of prototype verify the validity of the proposed three-factor method.

感应耦合电能传输系统的设计

针对感应耦合电能传输系统(ICETS)的互感模型,提出设计ICETS的三要素法：即通过耦合系数、可分离变压器原副边自感比值和副边能量接收电路的品质因数三要素设计ICETS.该方法在谐振状态下,将ICETS的特性参数表示为三要素的函数,根据可分离变压器的传输效率和器件应力要求进行系统设计.论文分析比较ICETS的4种补偿电路,并以原边串联补偿、副边并联补偿（SP）电路为例,设计输出功率为100 W的ICETS样机.结果表明,用三要素法设计ICETS,可分离变压器效率高,补偿电容电压应力小，样机实验证明所提三要素法的正确性.
