Power supply control method and device |
摘要 |
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. |

1. A power supply control loop, comprising:
a feed-forward digital control circuit configured to:
sample an input voltage to generate a sampled input voltage;perform anti-steady-state-disturbance processing on the sampled input voltage to generate a feed-forward input voltage; andoutput the feed-forward input voltage; and a feedback digital control circuit coupled to the feed-forward digital control circuit and configured to:
sample an output voltage to generate a sampled output voltage; andcombine the sampled output voltage and the feed-forward input voltage that is output by the feed-forward digital control circuit into a stability voltage. |
