SWITCHING CONVERTER

摘要

The invention relates to a switching converter for converting an input direct current (UE) into at least one output direct current (UA). According to the invention, an internal auxiliary voltage (UH1, UH2) is derived from at least one auxiliary winding (WHI, WH2) of a transformer (Tr), a controllable load element (BAL) is provided for the output current and a stop signal (SS) can be fed to the switching converter for disconnecting/connecting the output current. To connect the load element (BAL) to the output direct current, said stop signal is drawn on to such a magnitude that a condition similar to a short-circuit is produced, in which the output current (Ua) lies sufficiently close to nil, but the auxiliary voltage(s) (UH1, UH2) for supplying the units allocated thereto is sufficiently high.
