Abstract: A controlling method and device for a wireless power transfer system, wherein the wireless power transfer system includes a transmitting component and a receiving component, and further includes a contactless transformer & compensation (CT&C) circuit, and the controlling method includes: obtaining positional relationship information of the transmitting component and the receiving component; adjusting the number of coil turns of the transmitting component based on the positional relationship information, and making conditions of a CT&C voltage gain characteristic and an input impedance characteristic after a charging inverter bridge of the wireless power transfer system meet a charging condition. The abovementioned technical solution can provide a protection for a stable operation of the wireless power transfer system with a non-mechanical adjusting device, and the wireless charging can be achieved without using a mechanical adjusting device to align and range.

Abstract: The present disclosure discloses a circuit protection method. The method includes that: a voltage or a current sent by a sending end of a circuit protection apparatus is received, and a voltage value of the received voltage or a current value of the received current is sampled; when it is detected that the sampled voltage value or current value is in a first pre-set threshold range, a pre-set input control switch is controlled to be turned on, and an input of a voltage or a current of the sending end is received; the received voltage or the received current is converted and processed, and a voltage value of the processed received voltage or a current value of the processed received current is sampled; and when it is detected that the processed voltage value or the processed current value is in a second pre-set threshold range, a pre-set output control switch is controlled to be turned on, and the processed received voltage or the processed received current is allowed to be outputted. The present disclosure also discloses a circuit protection apparatus, a charging device and a computer storage medium.
