Title:
SWITCHING POWER SUPPLY, CONTROL CIRCUIT FOR SAME, BASE STATION, AND SERVER
Document Type and Number:
WIPO Patent Application WO/2021/106712
Kind Code:
A1
Abstract:
An error detector 204 generates an error signal err in accordance with the error between a feedback signal based on the output of a switching power supply 100 and the target value of the feedback signal. A compensator 210 generates a control command H so that the error signal err approaches zero. A pulse modulator 220 generates a pulse signal Sp in accordance with the control command H. An auto-tuner 240 automatically optimizes a parameter PARAM that specifies the response characteristics Gc(z)of the compensator 210. A degradation estimator 250 generates, on the basis of the automatically optimized parameter PARAM, information INFO about the degradation of the output capacitor COUT of the switching power supply 100.
