Classification: CPC G  H | IPC G

Claim 15:
16. The Ethernet power supply as claimed in claim 15, 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, the second control unit, and the path switch,
wherein the first valid control signal turns on the drive switch to turn on the path switch, and the turned-on path switch makes the drive switch in a turned-on state and continuously connect the coupling relationship between the power terminal and the bus positive terminal,
wherein the invalid control signal turns off the drive switch to turn off the path switch, and the turned-off path switch makes the drive switch in a turned-off state and continuously disconnect the coupling relationship between the power terminal and the bus positive terminal.
