The single inverter single transmitter multi-frequency and multi-receiver inductive wireless power transfer (WPT) system can simultaneously support multiple loads of different frequencies, with a simple structure and good compatibility, and has great potential for application. Its compensation network requires a large number of passive components, forming a high-order system with complex constraints, and thus the parameter design of high-power and high-efficiency compensation network faces enormous challenges. The dual-frequency LCC-S structure is taken as an example, and the design variables are reduced from seven to only one through analysis. In order to achieve high-power and high-efficiency transmission of the system, a dual-frequency compensation network design method based on differential evolution algorithm and Lagrange multiplier method is proposed, taking into account the influence of inductance parasitic resistances. Finally, an experimental prototype was constructed based on the design scheme obtained by this method. Experimental results demonstrate that the prototype can achieve load independence and constant voltage characteristics without relying on control methods, with a system output power of 165.83 W and a total efficiency of 94.05%.
