Abstract
A power supply control method and device and relates to the field of electronics, and can alleviate impact of a power supply input disturbance on an output voltage. A specific solution is as follows: sampling an input voltage to generate a sampled input voltage; performing anti-steady-state-disturbance processing on the sampled input voltage to generate a feed-forward input voltage; sampling an output voltage to generate a sampled output voltage; and combining the sampled output voltage and the feed-forward input voltage that is output by a feed-forward digital control circuit into a stability voltage. The present invention is applied to power supply control.
