AI Technical Summary

Technical Problem

Existing voltage regulation modules cannot accurately predict voltage drops based on load current change trends and initiate precise current compensation in advance, resulting in limited voltage response speed and a tendency for undercompensation.

Method used

By acquiring the load-side voltage signal in real time, calculating the real-time current gap, predicting the minimum point of transient voltage, and starting multiple branch injection loops for current compensation before the predicted voltage falls below the safe range, a binary weight distribution and smooth exit mechanism are adopted to ensure that the compensation current matches the gap and avoid overcompensation and voltage oscillation.

Benefits of technology

It achieves rapid response under drastic load current changes, reduces voltage downsurge, improves processor stability, reduces voltage fluctuations, and ensures a smooth transfer of injected energy.

Abstract

The application discloses a voltage regulation module injection method, system and medium, and relates to the technical field of processor power supply. The method comprises the following steps: collecting a load end original voltage signal and determining a load voltage signal; calculating a real-time current gap and predicting a transient voltage minimum point; when the predicted value is lower than the lower limit of a safe voltage range, selecting a switch tube combination according to the real-time current gap to perform current injection; and after the voltage rises back to a retreat threshold, closing the opened switch tubes one by one according to a preset time step. Through the prediction injection, binary weight current regulation and smooth retreat, the application reduces load transient voltage drop, reduces secondary oscillation and improves system stability.
