| 主权项 | 1. A wireless power transmitter comprising: a power supply configured to supply charging power; a power transmitter configured to transmit the charging power to a wireless power receiver; an overcurrent protection circuit configured to change an impedance of the wireless power transmitter; and a controller configured to: monitor a current value of an output terminal of the power supply, and connect the overcurrent protection circuit to the power transmitter if the monitored current value is greater than a predetermined threshold, wherein the current value of the output terminal of the power supply is decreased to a non-zero value less than the predetermined threshold, while the overcurrent protection circuit is connected to the power transmitter. | ||
