摘要

An inductive wireless power transfer system using magnetic coupling facilitates the transmission of energy from the primary coil to the secondary coil. Tracking maximum efficiency poses a significant challenge for this power transmission. This paper proposes an approach based on the fuzzy perturbation and observation technique, which demonstrates improved performance over traditional perturbation and observation methods for tracking efficiency. The duty cycle of a DC-DC converter on the secondary side is adjusted to optimize the load resistance observed from the rectifier input on the receiver. Additionally, since the load resistance that corresponds to maximum efficiency differs from that at the maximum power point, a DC-DC converter is employed on the transmitter side to achieve the necessary power level while maintaining maximum efficiency. This enables appropriate voltage adjustment on the receiver side, allowing the achievement of desired power alongside maximum efficiency. Simulation results from Simulink/MATLAB software confirm the successful execution of the proposed algorithm.
