Patent ID: 8035250

Claim:
A load sharing, multi-module power supply system for supplying power to a load, the system comprising: a first power supply module having a controller and having a first per unit capacity (pu-c); a second power supply module having a controller and having a second per unit capacity (pu-c); a third power supply module having a controller and having a third per unit capacity (pu-c); said controller of said first power supply module adapted to implement a reduction in an output power of said first power supply module upon the detection of an operating event, where a portion of said load being handled by said first power supply module is shed by a determined percentage, and such that said first power supply module remains operating during said operating event but at a reduced power output level; and upon the occurrence of said operating event, said controllers of said second and third power supply modules being adapted to increase their respective said power outputs so that each of said second and third power supply modules accommodates a subportion of said portion of said load that has been shed by said first power supply module, and when needed, such that said controllers of said second and third power supplies increase the power outputs of their respective said power supply modules by different amounts, when needed, such that said second and third power supply modules assume different additional percentages of the load that was shed by the first power supply module.
