Abstract:
1. A regulation voltage system for a power supply system comprising: a current sense system configured to generate a sense signal that represents an output current of the power supply system that is supplied to a load; and a positive voltage droop controller configured to provide a regulation voltage to the power supply system, the positive voltage droop controller setting the regulation voltage to one of a predetermined fixed reference voltage or a variable reference voltage based on the sense signal, the variable reference voltage being less than the predetermined fixed reference voltage, wherein the positive droop controller generates a variable positive droop voltage that increases as a function of the output current from approximately a predetermined minimum setpoint voltage to approximately the predetermined reference voltage when the output current is approximately equal to a threshold current, wherein setting a magnitude of the regulation voltage to be less than the predetermined reference voltage comprises setting the magnitude of the regulation voltage to approximately the positive droop voltage.
