Abstract

In order to improve the efficiency optimization control ability of wireless power transmission, the efficiency optimization control method of wireless power transmission based on double pick-up structure is proposed. The channel output switching control model of wireless power transmission is constructed. Combining power balance scheduling and load balance control methods, the efficiency optimization design of wireless power transmission is carried out, and the objective function of wireless power transmission efficiency optimization is constructed. Taking the steady-state output of load terminal voltage as the constraint target set of control object, the dual-pickup structure model of wireless power transmission efficiency optimization control is established by maximum power tracking and identification method, and the wireless power transmission efficiency parameter value near the maximum power point is obtained. Template feature matching and energy management optimization method are adopted to realize wireless power transmission efficiency optimization control. The simulation results show that the wireless power transmission efficiency control with this method has high output fitness level and good balance, improves the wireless power transmission efficiency, reduces the output power consumption and has good wireless power transmission adaptability.
