Power conversion device with electric arc suppression

A power conversion device, configured to be electrically coupled to a power source to provide power to an electronic device, comprising:

• a power supply connector, comprising a first ground pin, a power supply pin and a first detection pin respectively configured to be electrically coupled to a second ground pin, a power input pin and a second detection pin of a power input connector of the electronic device;
• a voltage conversion circuit, configured to be electrically coupled to the power source to provide power at an output voltage level suitable for the electronic device according to the power source;
• a switch circuit, electrically coupled to the voltage conversion circuit and the power supply pin;
• and
• a detection circuit, electrically coupled to the first detection pin, the voltage conversion circuit and the switch circuit for configuring the switch circuit to be conducted or non-conducted,
• wherein after the power supply connector is electrically coupled to the power input connector and the first ground pin and the second ground pin are fully shielded, the power supply pin and the first detection pin are electrically coupled to the power input pin and the second detection pin respectively;
• when the detection circuit detects the first detection pin is electrically coupled to the second detection pin, the detection circuit configures the switch circuit to be conducted, such that the voltage conversion circuit provides power to the electronic device through the switch circuit and the power input pin.
