Title:
POWER CONVERTER, POWER ADAPTER, ELECTRONIC DEVICE AND POWER CONVERSION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/070584
Kind Code:
A1
Abstract:
A power converter, a power adapter, an electronic device, and a power conversion method, which enable an output voltage of a conversion circuit to meet load requirements. The power converter comprises a first conversion circuit and a control apparatus that is connected to the first conversion circuit. The control apparatus may detect an output voltage of the first conversion circuit to obtain the voltage value of a first voltage; generate a slope compensation signal by using the voltage value of the first voltage; obtain an error signal according to an error between the voltage value of the first voltage and the voltage value of a reference voltage; compare the slope compensation signal with the error signal to obtain a comparison signal; and generate a driving signal of the first conversion circuit according to the comparison signal.
