Abstract

A circuit for a paralleled power supply module to implement automatic current-sharing in proportion comprises: at least two power supply modules, and an output current feedback loop and an output voltage adjusting loop corresponding to each power supply module. Wherein, the output current feedback loop comprises an output current sample amplifying unit, configured to collect output current of a power supply module and amplify the collected output current into a voltage signal according to an inverse proportion of the output proportion set for each power supply module, and a current-sharing controller unit configured to adjust an output voltage of each power supply module; and the output voltage adjusting loop is configured to compare the output voltage of the current-sharing controller unit with a reference voltage, and control the output voltage of the power supply module to adjust the output current.
