Title:
CONSTANT-POWER CONTROL APPARATUS AND METHOD FOR ELECTRONIC DEVICE, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/179242
Kind Code:
A1
Abstract:
Provided are a constant-power control apparatus and method for an electronic device, and a device and a storage medium, which belong to the technical field of computers. The constant-power control apparatus comprises: a voltage collection structure (110), which collects a power supply voltage of an electronic device; a current collection structure (120), which comprises a filter unit (121) and a sampling unit (122), wherein the current collection structure (120) performs current filtering by means of the filter unit (121), and performs current sampling by means of the sampling unit (122), so as to obtain the present sampling current; and a control structure (130), which is connected to the current collection structure (120) and the voltage collection structure (110) and is used for acquiring a current correspondence, wherein the current correspondence is used for representing the correspondence between different sampling currents and a power supply current corresponding to each sampling current (201); determining, from the current correspondence, the present power supply current corresponding to the present sampling current (202); determining a target power supply current on the basis of a target power and the power supply voltage (203); and adjusting the present power supply current to the target power supply current (204). The problem of it being impossible to achieve constant-power control on an electronic device can be solved, and constant-power output of the electronic device is realized.
