Abstract
An anti-leakage supply circuit includes a power supply unit, an output unit, a control unit, and a control circuit. The control unit is configured to output a control signal. The output unit is configured to be switched on after receiving the control signal and to output an output voltage after being switched on and receiving a voltage from the power supply unit. The control circuit is configured to be switched on after an electronic device is in a normal state. The output unit is configured to connect to the interface after the control circuit is switched on, thereby enabling the output unit to output the output voltage to supply to an interface. The control circuit is further configured to be switched off after the electronic device is in a shutdown state, thereby disabling the output voltage supply to the interface.
