A one-way conduction device includes a first transistor and a driving circuit. The driving circuit includes a first circuit, a second circuit and a detection circuit. The first transistor is coupled between an input end and an output end of the one-way conduction device. In the first circuit, a first conduction unit is coupled between the input end of the one-way conduction device and a first resistor. In the second circuit, a second conduction unit is coupled between the output end of the one-way conduction device and a second resistor. In the driving circuit, the detection circuit detects whether a current flows from the first circuit to the second circuit, and accordingly turns on or turns off the first transistor. In this manner, the driving circuit can control the turning on and off of the one-way conduction device.
