System for maintaining power efficiency of power supply modules by selectively connecting and disconnecting power supply modules from a plurality of power supply modules based on the calculated power supply module output to input ratio of each module
A power supply system for supplying power to a number of loads includes a number of power supply modules, a bus, and a control module. The power supply modules each comprises an input terminal receiving an input power and an output terminal outputting an output power, the input terminals of power supply modules having the same input power. The bus is configured for connecting the loads to the power supply modules. The control module calculates the ratio of the total output power of the power supply modules to the input power of one power supply module and controls the connection and the disconnection of the power supply modules according to the ratio.
