<p>The voltage converter has an input circuit provided by the primary winding (WO) of a transformer (Tr) in series with a switch (SO) controlled by a regulator (RSO) across a DC input voltage (UE). The transformer has at least 2 secondary windings (L1, L2, L3), providing respective output voltages (UA1, UA2, UA3) via respective rectifiers (D1, D2, D3), regulators RS1, RS2, RS3) and capacitors (C1, C2, C3). The regulator (RS1) of one output circuit is coupled to the input circuit regulator for controlling the pulse ratio and/or the frequency of the control pulses for the switch, each other output circuit having a controlled switch (S2, S3) controlled by the respective regulator (RS2, RS3) in dependence on the corresponding output voltage (UA2, UA3).</p> |
