Title:
OUTPUT POWER CONTROL METHOD OF POWER-DELIVERY DEVICE INCLUDING PLURALITY OF POWER SUPPLY INTERFACES, AND POWER-DELIVERY DEVICE OF SAME
Document Type and Number:
WIPO Patent Application WO/2022/197067
Kind Code:
A1
Abstract:
A power-delivery device comprising a plurality of power supply interfaces is disclosed, the power-delivery device comprising: an AC/DC converter; a plurality of DC/DC converters having a first output power of a first voltage and a first current; and a main control circuit electrically connected to the AC/DC converter and the plurality of DC/DC converters, wherein the main control circuit receives connection state information of an external device connected to the plurality of power supply interfaces, determines, on the basis of the connection state information, whether there exists a specific DC/DC converter, which requests output of a second output power greater than the first output power, from among the plurality of DC/DC converters, and controls, when the specific DC/DC converter requesting the output of the second output power exists, the specific DC/DC converter so that a voltage output from the AC/DC converter is directly supplied to the specific DC/DC converter, wherein the voltage output from the AC/DC converter is changed on the basis of the connection state information. Various other embodiments identified by the present document are possible.
