The invention relates to a wireless energy receiver and a dynamic wireless energy constant voltage output system. The receiver comprises a pickup coil, a relay coil and a magnetic shielding layer, and the relay coil comprises a first sub-coil and a second sub-coil; the first sub-coil and the second sub-coil are electrically connected in series and located on the two sides of the magnetic shielding layer respectively, the first sub-coil is used for being coupled with the energy transmitting coil to achieve wireless energy pickup, and the second sub-coil is used for being coupled with the pickup coil and transmitting the picked energy to the pickup coil to supply power to a load; and the first sub-coil is of a double-D-shaped coil structure with the same size, the current directions in the double-D-shaped coil structure are opposite, the second sub-coil is of a square coil structure, and the pickup coil and the second sub-coil are the same in structure. The system has the advantages that: the receiving end forms a double-S topological structure and can be matched with the multi-S topology of the transmitting end to form the dynamic wireless energy constant-voltage output system, so that the constant-voltage output characteristic of the receiving end is effectively kept, the number of components is reduced, the system structure is simplified, and the design cost is saved.

    本发明涉及一种无线能量接收器及动态无线能量恒压输出系统,接收器包括拾取线圈、中继线圈和磁屏蔽层,中继线圈包括第一子线圈和第二子线圈;第一子线圈和第二子线圈电性串联并分别位于磁屏蔽层的两侧,其中第一子线圈用于耦合能量发射线圈实现无线能量拾取,第二子线圈用于耦合拾取线圈并将拾取的能量传递至拾取线圈为负载供电;第一子线圈为尺寸相同的双D型线圈结构,该双D型线圈结构中的电流方向相反,第二子线圈为方形线圈结构,拾取线圈与第二子线圈结构相同。其效果是:接收端形成双S拓扑结构,可配合发射端多S拓扑构成动态无线能量恒压输出系统,从而有效保持接收端恒压输出特性,节省元器件数量,简化系统结构,节约设计成本。
