<p>A load sharing apparatus for accurately sharing load between a plurality of power supplies (1, 2) comprises one or more load sharing modules (Sharel, Share2), each for association with a respective power supply. Each load sharing module comprises load determining means for generating a signal which represents a load value corresponding to the power or current supplied by the respective power supply, and voltage control means for controlling the output voltage of the respective power supply to vary inversely with the load value at a first rate when the load value is below a threshold value, and for controlling the output voltage of the respective power supply to vary inversely with the load value at a second rate when the load value equals or exceeds the threshold value. The second rate is greater than the first rate</p> |
