Abstract

In this paper, a compensation network parameter design method based on multi-objective optimization algorithm has been proposed to meet the robust requirements of the output characteristics of wireless power transfer (WPT) system under non-resonant conditions. The equivalent circuit mathematical model of WPT system under non-resonant condition is established, and the sensitivity of system output characteristics to different component parameters is analyzed. A compensatory topology parameter optimization method of double-sided LCC based on NSGAII algorithm is proposed, which effectively reduces the system output power fluctuation when multiple parameters fluctuate together, improves the output characteristics of the double-sided LCC WPT system, and enhances the robustness of the system output. Finally, the proposed method is validated by comparing the power variation before and after the system parameter optimization under the condition of multi-parameter combined fluctuation and the condition of sensitive parameter random fluctuation. It has lower power variation when component parameter fluctuates randomly and it improves the controllability of the system to a certain extent.
