Patent ID: 7895455

Claim:
A method for dynamically managing power consumption in a computer system having at least two parallel power converters, comprising: determining a maximum power capacity for each of the power converters; monitoring power consumption of the computer system; dynamically measuring an input power associated with each of the power converters over time; saving samples of the measured input power over time to dynamically generate an efficiency curve to determine the most efficient operating range for each of the power converters; selectively turning off one or more of the power converters based on the most efficient operating range determined for each of the power converters if the power consumption of the computer system can be provided by less than all of the parallel power converters, such that a reduced number of parallel power converters remains turned on; determining a reduced maximum power capacity of the reduced number of parallel power converters; setting a power cap value for the computer system that is less than or equal to the reduced maximum power capacity; and throttling the computer system if power consumption of the computer system reaches the power cap value to prevent power consumption of the computer system from exceeding the reduced maximum power capacity.
