Abstract: A USB control apparatus is connected between a power supply and an external interface, and the USB control apparatus includes a first connection port connected to the power supply; a second connection port connected to the external interface; a control unit connected to the first connection port; and a first conversion unit connected between the control unit and the second connection port. The control unit detects a power source outputted from the power supply and outputs first information to the first conversion unit. The first conversion unit detects the type of a connection port of the external interface. The first conversion unit converts the first information into second information corresponding to the connection port of the external interface to the second connection port.

Abstract: A test device and a method are provided in the invention. The test device includes a first connection interface, a storage device, a processor and a second connection interface. The first connection interface is coupled to a device under test (DUT) and obtains power information from the DUT according to a first instruction. The storage device stores the power information. The processor is coupled to the first connection interface and storage device, when the first connection interface is coupled to the DUT, sends the first instruction to the first connection interface, receives the power information from the first connection interface, and stores the power information in the storage device. The second connection interface is coupled to an external controlling system, sends the power information to the external controlling system and receives a test instruction from the external controlling system to test the DUT.

Abstract: A power delivery device and a control method are shown. The power delivery device includes a power conversion circuit, a power factor correction circuit, and an output voltage control circuit. The power conversion circuit includes a primary side and a secondary side, and is configured to receive an input voltage and convert the input voltage to an output voltage. The power factor correction circuit is electrically coupled to the primary side and configured to increase the power factor of the power delivery device. The output voltage control circuit is electrically coupled to the secondary side and configured to control the voltage level of the output voltage. When the voltage level of the output voltage is lower than a predetermined level, the power factor correction circuit is deactivated.
