The invention discloses a wireless charging power supply manager, which comprises a receiving circuit, a switching power supply chip circuit, a switching tube protection circuit, a high-voltage end overcurrent protection circuit, a charging voltage control process circuit, an adapter control unit circuit and an overload protection circuit of a storage battery, the wireless charging power supply manager is characterized in that the L1 resonance inductance coil receives energy sent by the transmitting wire coil, the capacitor C0 and the resonance inductance coil L1 are in parallel resonance, andthen the L1 resonance inductance coil and the capacitor C0* form series resonance to boost resonance voltage again. According to different relative positions between the transmitting wire coil and the receiving wire coil, the transmitting host can determine resonant frequency output under the current distance according to comprehensive parameters such as output resonant frequency, resonant current, power input current and power input voltage; and triple protection is performed simultaneously.
本发明公开了一种无线充电电源管理器,包括接收电路、开关电源芯片电路、开关管保护电路、高压端过流保护电路、充电电压控制过程电路、适配器控制单元电路、电瓶的过载保护电路,其特征在于:所述接收电路由L1谐振电感线圈接收到发射线盘发送过来的能量,电容C0和谐振电感线圈L1并联谐振,再和电容C0*组成串联谐振将谐振电压再次提升。本发明可根据发射线盘和接收线盘两者之间的相对位置远近不同,发射主机会依据输出谐振频率、谐振电流、电源输入电流、电源输入电压等综合参数,确定当前距离下的谐振频率输出;三重保护同时进行。
