Abstract In order to solve the problem of complex control and large loss of monitoring mode of all-directional wireless charging back-end, this paper firstly designs a conical coil arrangement mode, and proposes the maximum power tracking (MPPT) strategy based on sepic circuit through theoretical analysis. On this basis, a front-end monitoring system of load position based on adaptive control algorithm is proposed. Through signal acquisition on the transmitting side, real-time and accurate monitoring of load position can be effectively realized. Finally, an experimental prototype is designed to verify the feasibility of the system.

Key words： wireless charging all-direction front-end monitoring
