Referring to fig. 7, when the electronic device 100 is an energy emitting terminal, the battery 160 may output the charging energy E1 to the voltage regulating circuit 191. The voltage regulator circuit 191 may perform a voltage regulation operation, such as a boosting operation, on the charging energy E1, and then supply the charging energy E1 to the power switching circuit 192 to perform dc-to-ac switching. Thereafter, the charging controller 193 may cause the transmitting coil 120 to transmit the charging energy E1 out to the sensing coil 210 of the object to be charged 200 for wirelessly charging the object to be charged 200.
Referring to fig. 8, when the electronic device 100 is an energy receiving end, the charging controller 193 may receive the charging energy E2 transmitted by the other electronic device 300 through the receiving coil 180, and switch the received charging energy E2 from ac to dc through the power switching circuit 192. Then, the power switching circuit 192 outputs the charging energy E2, which has been switched, to the voltage regulating circuit 191. The voltage regulator circuit 191 is configured to perform a voltage regulation operation, such as a voltage stabilization operation, on the charging energy E2, and then output the charging energy E2 to the battery 160 to wirelessly charge the battery 160.
In some embodiments, the voltage regulating circuit 191, the power switching circuit 192 and the charging controller 193 may be disposed on the pcb B1 or the motherboard 150, respectively, but the disclosure is not limited thereto.
