Abstract

A power transmission cable and a power transmission apparatus are provided. The power transmission cable comprises a Universal Serial Bus (USB) Type-C interface, a control circuit, and a Direct Current (DC) output terminal, wherein the control circuit is electrically connected to the USB Type-C interface and the DC output terminal. When the USB Type-C interface is connected to a USB Power Delivery(PD) transformer, the control circuit performs a handshake procedure with the USB PD transformer according to a USB PD protocol to confirm a designated voltage value. After the handshake procedure, the USB Type-C interface receives a power with the designated voltage value from the USB PD transformer and the DC output terminal outputs the power.

Description

technical field [0001] The present invention relates to a power transmission line and a power transmission device; more specifically, the present invention relates to a power transmission line and a power transmission device related to Universal Serial Bus Power Delivery (USB PD). Background technique [0002] In recent years, Universal Serial Bus (USB) technologies have developed rapidly, and the two most critical technologies are the USB Type-C interface and the Universal Serial Bus Power Delivery (PD) protocol. At present, there are transformers that combine the USB Type-C interface and the USB Power Transfer Protocol. The transformer can output power with a voltage value ranging from 3 volts to 20 volts through its USB Type-C interface, and its maximum output power can reach 100 watts. Since such a transformer can provide a wide voltage range of electric power, the industry expects it to be widely used as a power supply device. [0003] Although the voltage value of th...
