Abstract (en)
[origin: WO0197368A2] The invention relates to a switching converter for converting an input direct current (UE) into an output direct current (UA). Said converter is provided with at least two primary windings (L1... L4; W1, W2) of a transformer (Tr) and each primary winding is connected to an input capacitor (C1... C4; C11 + C12; C21 + C22) by means of at least one controlled switch (T1... T4; T11... T22). The input capacitors are connected to the input direct current (UE), together with the series connections of the primary windings with their controlled switches that are connected in series. A control circuit (AST) is configured to simultaneously open or close all the controlled switches.
