| 摘 要： | 效率是非接触电能传输系统研究的一个热点,适当的二次侧并联补偿电容能够提高系统的效率,但加入二次侧补偿电容容易使系统进入多谐振频率状态.本文从非接触电能传输系统的高阶数学模型出发,描述了频率分叉现象,并且用数值方法界定了分叉区域.文章最后提出了一种在频率分叉现象下的二次侧并联补偿电容选择方法,实验证明基于这种方法选择的并联补偿电容能使系统传输效率显著增大.

| Abstract: | Contact-less power transmission system is suitable for the energy transmission under flammable environments,because of its spark free and no uncovered conductors. Optimal parallel capacitor at secondly side can enhance the efficiency of contact-less power transmission system, but the parallel capacitor make the system easily to have multi-resonant frequency when load changes. This paper on the basis of high order mathematic model, described the frequency bifurcation phenomenon, and used numerical method to bound the bifurcate region of parameter. We also advanced a way to choice the secondly side parallel capacitor, and the experiment results were given at the end of this paper. |
