Abstract:
1. A junction box for connecting a power supply unit of a power system, the junction box comprising: a first connection terminal and a second connection terminal for connecting another junction box in a serial connection; at least one bypass diode electrically coupled to the power supply unit; a serial carrier interface module electrically coupled to the first connection terminal and the second connection terminal for transmitting a carrier and a DC power provided by the power supply unit; a switch disposed in the serial carrier interface module for turning on and turning off the DC power; and a control module electrically coupled respectively to the serial carrier interface module and the switch for receiving the carrier and switching the switch according to the carrier so as to control the transmission of the DC power, wherein the serial carrier interface module comprises a carrier line and a power line, the carrier line is electrically coupled to the first connection terminal and the second connection terminal for transmitting the carrier and has a first inductor and a capacitor connected to the first inductor in a serial connection for forming a resonance circuit, and the power line is electrically coupled to the first connection terminal and the second connection terminal connected in parallel with the carrier line for transmitting the DC power, and the switch is disposed on the power line for turning on and turning off the power line.
