Abstract
A power supply system for maintaining the efficiency of an AC/DC power conversion unit in relation to a load is disclosed. The load varies in response to power usage during operation of the power supply system. An AC power input and a DC power output of the power conversion unit direct DC power to attached components. A master controller disposed in the power supply system detects the load of an attached computer system through a DC meter and executes an algorithm to determine the values of circuit parameters of conversion circuits in the AC/DC power conversion unit. The master controller sends the values to a mode controller through a digital signal interface. The mode controller adjusts the operating mode of the conversion circuits and thus changes the efficiency of the AC/DC power conversion unit.
