摘 要:针对双线圈并联的高功率感应耦合电能传输(ICPT)系统存在线圈间补偿电流不均衡问题,提出一种分布式补偿电流均衡方法。首先提出了双线圈并联ICPT系统的分布式补偿网络,然后依据等效思想和迭代思想提出补偿电流均衡方法,根据该方法求解得到补偿参数和各线圈补偿电流表达式,再将该方法拓展到n线圈并联结构。在北京超算云计算中心的COMSOL云平台验证了所提出的方法不仅有效均衡了各线圈的补偿电流,而且谐振状态受参数漂移的影响程度并未因补偿网络的复杂程度增加而增加。最后搭建了实验平台,验证了所提方法的有效性。A distributed compensation current equalization method was proposed to solve the problem of unbalanced compensation current of each coil in high power inductively coupled power transmission(ICPT)system with double-coil in parallel.Firstly,the distributed compensation network of the double-coil parallel ICPT system was proposed,and then the compensation current equalization method was proposed based on equivalent and iterative ideas.The compensation parameters and the current compensation expressions of each coil were obtained with the method,and then the method was extended to the n-coil parallel structure.Secondly,the COMSOL cloud platform of the Beijing Supercomputer Cloud Computing Center verified that the proposed method balanced the compensation current of each coil effectively and that the influence of the resonance state on the parameter drift did not increase with the increase of the complexity of the compensation network.Finally,an experimental platform was built to verify the effectiveness of the proposed method.
