Classification: CPC G  H | IPC G

Claim 13:
14. The Ethernet power supply as claimed in claim 3, wherein the path control circuit comprises:
a path switch, a first end of the path switch coupled to the bus positive terminal and a second end of the path switch coupled to the power terminal, and
a drive switch, a first end of the drive switch coupled to a control end of the path switch, and a control end of the drive switch coupled to the first control unit and the second control unit,
wherein the first control unit and the second control unit are configured to turn on or turn off the path switch, and the drive switch is configured to turn on or turn off the path switch; the drive switch is turned on by the first control unit according to the first control signal when the first control unit is in the temporary connection phase or is turned on by the second control unit according to the second control signal, and the turned-on drive switch turns on the path switch to connect the coupling relationship between the power terminal and the bus positive terminal;
wherein the first control unit and the second control unit of the second control module turn off the drive switch when the negative end is disconnected from the bus negative terminal, and the turned-off drive switch turns off the path switch to disconnect the coupling relationship between the power terminal and the bus positive terminal.
