Claim 9:
10. A method for adjusting alternating current (AC)-direct current (DC) (AC-DC) converter output voltage, the method comprising:
monitoring, by a plurality of controllers, a system controller that communicates with the plurality of controllers, and a constant current source, events for connection/disconnection, new profile request from one or more loads and storing respective port power profile, the plurality of controllers coupled to a corresponding plurality of ports to operate the one or more loads, at least one controller of the plurality of controllers is a master controller, an AC-DC converter, and a plurality of DC-DC converters, other plurality of controllers being slave controllers, the constant current source being coupled to the AC-DC converter and the plurality of controllers, and the system controller only communicates with the plurality of controllers and the constant current source;
determining, at the master controller or the system controller, input signals pertaining to parameters of power levels, from the slave controllers, for each port of the corresponding plurality of ports based on the one or more loads that are connected to the corresponding plurality of ports, the power levels including current and voltage;
calculating, at the master controller, based on the parameters, an optimal input voltage value for the plurality of DC-DC converters based on a highest requested voltage by one or more ports of the plurality of ports, the plurality of DC-DC converters coupled to the plurality of controllers, an optimal input voltage is equal to the highest request voltage plus the adjusted voltage; and
communicating, by the master controller, the optimal input voltage to the AC-DC converter through the constant current source, the master controller reads input voltage of the plurality of DC-DC converters through digital communication to adjust the constant current source output coupled to an AC-DC converter feedback circuit through the digital communication till the input voltage of the plurality of the DC-DC converters reaches the optimal input voltage,
wherein, in response to the optimal input voltage, the AC-DC converter regulates an amount of DC voltage that is being supplied to the plurality of DC-DC converters to operate the one or more loads, and
wherein the constant current source is directly connected to the system controller and each controller of the plurality of controllers.
