摘要：
This work constructs a circuit model, forms a resonant frequency expression of the WPT system, and investigates a novel single side hybrid frequency adjusting strategy. Firstly, by the tracking strategy of minimizing the reflection coefficient, a novel hybrid frequency adjusting control strategy is exerted in the transmitting side by uniting the Bang-Bang control method and the fuzzy PID control technique. Secondly, the receiver is permitted to move to nearly any location within the system's working scope, and the system still reaches a near constant efficiency and a maximum load power. Finally, the simulation results verify that the proposed hybrid adjusting method can be adopted to track the resonant frequency more rapidly and more accurately.
