Abstract: A power delivery device and a control method are shown. The power delivery device includes a power factor correction circuit, and an output voltage control circuit. The power factor correction circuit is configured to increase a power factor of the power delivery device. The output voltage control circuit is configured to control an output voltage of the power delivery device, and detect an output current of the power delivery device. The power factor correction circuit is uncontrolled by the output voltage control circuit in response to a first load state of the power delivery device, and is controlled by the output voltage control circuit in response to a second load state of the power delivery device.

Abstract: A module comprising a USB Type-C receptacle, a USB Type-C plug and a logic unit is disclosed. A power pin of the receptacle is connected with another power pin of the plug via a switch. A CC pin of the receptacle is connected to ground through a pull-down resistance. Another CC pin of the plug is connected to the logic unit through a pull-up resistance. The module connects with a power source device being a power sink-role in order to receive a source capability of the power source device, then turns on the switch and transforms itself to a power source-role. The module connects to a DRP device afterward being the power source-role to act for the power source device and perform a USB PD communication with the DRP device.

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.
