Abstract
Abstract 1. A current supply circuit comprising a switched-mode converter (G1, G2) which is fed from a constant-current source (E, E) and is used as a d. c. voltage converter, comprising a transformer (Ü) and also at least one controllable switch (T1, T3), and a controller (R) for pulse width control, characterized in that a further controllable switch (T2) which is pulse-width controlled by the controller (R) is arranged in parallel with the input (E) of the d. c. voltage converter and that the controllable switches (T1, T2, T3) are controlled such that they are never simultaneously conductive.
