摘要：A circuit for a paralleled power supply module to implement automatic current-sharing in proportion comprises: at least two power supply modules, and an outputcurrent feedback loop and an output voltage adjusting loop corresponding to eachpower supply module. Wherein, the output current feedback loop comprises an outputcurrent sample amplifying unit and a current-sharing controller unit. The output currentsample amplifying unit is configured to collect output current of a power supply module,and amplify the collected output current into a voltage signal according to an inverseproportion of the output proportion set for each power supply module; the current-sharing controller unit is configured to adjust an output voltage of each power supplymodule; and the output voltage adjusting loop is configured to compare the outputvoltage of the current-sharing controller unit with a reference voltage, and control theoutput voltage of the power supply module to adjust the output current. Through thecircuit in the present embodiment, power supply modules at different power levels can

be made work according to set output proportion.
