Abstract
The direct current converter has a first circuit stage (1) with an active component (S0) for switching electrical currents and at least one inductance (L) and a second circuit stage (2) provided with at least 2 load outputs, at least one switching component (S1,S2,S3) connected in series with each of the latter, the switching components for the different load outputs connected in parallel with one another. An independent claim for an operating method for a direct current converter is also included.
