Problems solved by technology

[0003] Disadvantages of the existing technical solution: when the peripheral demand voltage changes, the output voltage of the PD adapter also changes, and the frequent switching of the input voltage has a negative impact on the stability and reliability of the DC-DC
If the PD decoy is used to trick out a voltage higher than 5V and then supply power to peripherals through DC-DC step-down, although it can solve the defects of the above usage scenarios, when the peripheral needs a large power (such as 30W or more), it will be due to DC-DC efficiency and other reasons lead to the problem of increased heat consumption and low power utilization in the system
[0004] Therefore, it is necessary to improve the Type-C PD power supply method and device to avoid the problem of system overheating and low power utilization when the peripheral device requires a large power

Abstract

The invention belongs to the technical field of Type-C power supply, and discloses a Type-C power supply method and device.The Type-C power supply method comprises the steps that an adapter supplies power to a DC-DC module, and the DC-DC module outputs voltage to a PD control module; the adapter negotiates with the PD control module to enable the adapter to output first power; the PD power supply module receives the peripheral demand voltage fed back by the PD control module and judges whether the peripheral demand voltage is larger than or equal to a first threshold value or not, if the peripheral demand voltage is larger than or equal to the first threshold value, the negotiated first power is divided into second power and third power, the third power is transmitted to the second female seat through the Bypass circuit, and the second female seat is connected with the second female seat through the Bypass circuit. Therefore, the second female seat supplies power to the peripheral. The adapter has the beneficial effects that when the required power of the peripheral is relatively high, the adapter directly supplies power to the peripheral through the Bypass circuit, so that power conversion of the DC-DC module is avoided, the system heating is reduced, and the utilization rate of the power supply is improved.

Description

technical field [0001] The present invention relates to the technical field of Type-C power supply, in particular to a Type-C power supply method and device. Background technique [0002] In the existing technical solution, for the system using Type-C PD power supply, in addition to supplying power to itself, it also needs to supply power to external devices. In the existing technical solutions for docking stations, the method of directly supplying power through the PD adapter is mostly used: that is, according to the external According to the power receiving requirements of the device, the power output suitable for the peripheral device is negotiated through the CC and the PD adapter; the power supply of the docking station itself is realized through DC-DC step-down from the PD adapter. [0003] Disadvantages of the existing technical solutions: when the voltage demanded by the peripheral device changes, the output voltage of the PD adapter also changes accordingly, and the...
