摘　　要：针对阻抗不匹配引起感应电能传输系统谐振频率不稳定的问题,提出了用于动态调谐的三电容组态阵列,分析了谐振电容与系统频率的关系以及电容阵列的容值分布、范围、输出精度,并采用遗传算法对三电容阵列的电容值进行优化.仿真实验结果表明,文中所提出的三电容阵列可获得较宽的输出电容范围及较高精度的可调电容值,适用于对输出电容值范围及可调精度要求较高的系统.In order to overcome the instable resonance frequency of inductive power transmission system caused by impedance mismatch,a three-capacitor configuration array for dynamic tuning is proposed,and the relationship between resonant capacitance and system frequency is analyzed. Moreover,the value distribution,scope and output precision of capacitor array are discussed,and the capacitance value of the three-capacitor array is optimized by means of genetic algorithm. Simulated results indicate that, as the proposed three-capacitor array presents wide-scope output capacitance and high-precision adjustable capacitance, it can be applied to the system that requires large output capacitance range and high adjustable precision.
