Abstract: A power supply system with current sharing includes a current sharing bus, a plurality of power supply units, and a plurality of controllers. The power supply units are connected to each other through the current sharing bus. Each power supply unit provides a current sharing signal value to the current sharing bus, and provides an output current to a load. Each controller receives current sharing signal values provided from other power supply units and current signal values corresponding to the output currents. When determining that the current signal value is less than a reference current sharing signal value, the controller increases an output voltage of the power supply unit to increase the output current. Otherwise, the controller decreases the output voltage to decrease the output current so that so that the output currents of the power supply units are shared to supply power to the load.

Abstract: A method of updating power firmware is applied to update power firmware when a power supply is powered. The method is executed by a microcontroller of the power supply, and the method includes steps of: planning a memory space in the microcontroller as a first space and a second space, wherein the first space stores a first program currently executing the power supply required by the power supply, emptying the second space before the power firmware is updated, writing a second program stored in a management system into the second space, switching the second space to the first space to complete updating the power firmware after the second program is completely written into the second space, and continuously outputting working power.
