Title:
APPARATUS, METHOD AND SYSTEM FOR ADJUSTING VOLTAGE STABILIZATION OUTPUT OF POWER SOURCE
Document Type and Number:
WIPO Patent Application WO/2022/105254
Kind Code:
A1
Abstract:
An apparatus, method and system for adjusting a voltage stabilization output of a power source (10). The power source (10) forms an output voltage according to a power supply current. The apparatus comprises a sampling module (11), a PID adjustment module (12) and a control module (13), wherein the sampling module (11) is used for sampling an output voltage of the power source (10), so as to obtain a sampled voltage (S100); the PID adjustment module (12) is used for obtaining a switching frequency signal on the basis of the sampled voltage and a preset control parameter by means of PID control adjustment, wherein the PID control adjustment comprises voltage-loop control adjustment and voltage-difference-change-rate loop control adjustment (S200); and the control module (13) is used for forming a power supply current according to the switching frequency signal (S300). The voltage stabilization output of the power source (10) can be realized.
