Patent ID: 7646116

Claim:
A method of balancing power-distribution in a direct current to direct current (DC to DC) power-conversion system, the power-conversion system comprising a plurality of channels connected to a load, the plurality of channels connected to a corresponding plurality of power sources, the method comprising: determining a first current based on a load current required at the load and a plurality of currents provided by the plurality of channels to the load, wherein the plurality of currents correspond to power outputs provided by the plurality of channels to the load; outputting a first power when the first current is at least equal to a first threshold, wherein the first power is a maximum power of a first power source of the plurality of power sources, and wherein the first power source is connected to a first channel of the plurality of channels; outputting a second power when the first current is less than the first threshold, wherein the second power is calculated based on the first current; computing a reference power based on at least one power output of a plurality of power outputs, wherein the plurality of power outputs correspond to the plurality of channels; outputting the first power when the reference power is at least equal to the first power; and outputting the reference power when the reference power is less than the first power.
