Abstract
The invention relates to a power supply circuit comprises several power supply modules for supplying power to various sub-assemblies and/or interfaces of electrical equipment, e.g. a communications equipment or a personal computer, in addition to a regulating circuit that regulates a first power supply module. The regulating circuit is connected to the power supply outputs of those power supply modules, between which a maximum voltage differential deviates from a reference value, the first power supply module is corrected in such a way that the deviation is minimized.
