Title:
OUTPUT OVER-VOLTAGE PROTECTION METHOD AND DEVICE FOR POWER SOURCE PARALLELIZED SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2017/148238
Kind Code:
A1
Abstract:
An output over-voltage protection method and device for a power source parallelized system, and a storage medium. The method comprises: detecting a real-time loop control voltage of each power source module of a power source parallelized system (201); determining, according to the detected real-time loop control voltage, whether there is a power source module having an over-voltage fault (202); and if there is a power source module having an over-voltage fault, controlling the power source module having an over-voltage fault to perform over-voltage protection (203). Thus, by means of the method, a power source module actually having a fault can be precisely found out according to a detected real-time loop control voltage, and over-voltage protection is individually performed on a power source module having an over-voltage fault, without influencing the normal operation of the other power source modules in a system, thereby improving the reliability of a power source parallelized system.
