Abstract:
1. Load sharing apparatus for load sharing between a plurality of power supplies, the apparatus comprising a plurality of load sharing modules, each for association with a respective power supply, each load sharing module comprising: a load determining module to generate a signal which represents a load value corresponding to the power or current supplied by the respective power supply; and a voltage control module to control an output voltage of the respective power supply to vary inversely with said load value at a first rate when the load value is below a first threshold value based on a maximum load rating of the respective power supply, and to control the output voltage of the respective power supply to vary inversely with said load value at a second rate when the load value equals or exceeds said first threshold value based on the maximum load rating of the respective power supply; wherein said second rate is greater than said first rate.
