ABSTRACT:
The invention relates to a circuit arrangement for supplying a DC voltage to be maintained constant to electric loads, at least one load being connected via a switching regulator to a supply loop fed with an impressed current. The circuit maintains its regulation even if the loads fluctuate greatly within a short time. Accordingly, the invention provides, that at the switching regulator the switching element is arranged parallel to the input; that between the switching element and a capacitor lying parallel to the output of the switching regulator a diode is arranged which is cut off when the switching element is conducting. The circuit arrangement can be used to advantage in power supply equipments of electric communications systems.
