In view of the problem that the performance characteristics of the high frequency inverter cannot be optimally matched with the technical specifications of the MCR-WPT system, this paper first analyzes and summarizes the characteristics of the high frequency inverter in the MCR-WPT system, and then establishes the comprehensive performance characteristic index system based on the energy-efficiency characteristic index, frequency characteristic index and dynamic characteristic index of high frequency inverter. Then, the fuzzy comprehensive evaluation method is used to propose an evaluation model of the high frequency inverter’s performance in the MCR-WPT system. Finally, the resonant wireless charging of the power line UAV is taken as the application scenario, and quantitatively evaluates the comprehensive performance of the two high-frequency inverters, and the analytic hierarchy process is used to determine the target weight of each evaluation index, the specific numerical evaluation results are obtained, which verifies the rationality and reliability of the quantitative evaluation method.
