<p>Switching converter to convert an input direct current (U<SUB>E</SUB>) into at least one output direct current (U<SUB>A</SUB>), wherein an internal auxiliary voltage (U<SUB>H1</SUB>, U<SUB>H2</SUB>) is derived from at least one auxiliary winding (W<SUB>H1</SUB>, W<SUB>H2</SUB>) of a transformer (Tr), a controllable load element (BAL) is provided for the output voltage, and a stop signal (s<SUB>s</SUB>) can be fed to turn the output voltage of the switching converter ON/OFF, which is used to connect the load element (BAL) to the output direct current to such an extent that a short-circuit-like condition is produced, in which the output voltage (U<SUB>a</SUB>) is adequately close to null, but the at least one auxiliary voltage (U<SUB>H1</SUB>, U<SUB>H2</SUB>) is adequately high to supply the units associated therewith.</p> |
