Abstract

A wireless charging system with double detecting circuits comprises a detecting circuit connected to an inductive loop to detect the induced electric field of the inductive loop; an auxiliary detection circuit connected to a power loop to detect the induced electric field of the power loop, wherein when the waveform detected by the detecting circuit is not applicable, it is replaced by the waveform detected by the auxiliary detecting circuit in order to determine the condition of the electrical receiver device and thus adjust the output to the inductive loop from the power loop.

Description

technical field [0001] The present invention relates to a charging system, in particular to a wireless charging system. Background technique [0002] Wireless charging is also called inductive charging and non-contact inductive charging. It uses near-field induction, that is, inductive coupling, to transmit energy from the power supply equipment to the power-consuming device. The device uses the received energy to charge the battery and simultaneously for its own operation. Since energy is transmitted between the charger and the power-consuming device through inductive coupling, there is no need for wires to connect the two, so that both the charger and the power-consuming device can have no exposed conductive contacts. [0003] Specifically, there is a coil in the wireless charging charger, which is driven by alternating current to generate an alternating electromagnetic field. There is another coil in the electric device that receives the alternating electromagnetic field...
