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 compen-sation 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 Supercom-puter Cloud Computing Center verified that the proposed method balanced the compensation current of each coil effec-tively and that the influence of the resonance state on the parameter drift did not increase with the increase of the com-plexity of the compensation network.Finally,an experimental platform was built to verify the effectiveness of the pro-posed method.
