Abstract

1. Method for the regulation and current limitation of a direct current ringing choke converter by means of a pulse-width-controlled electronic switch (6), which is periodically ignitable under external control and extinguishable in dependence on a comparator signal, wherein a reference voltage (Uref) and an evaluation signal are compared for the formation of the comparator signal and wherein the evaluation signal is formed from the sum of a signal for the output magnitude to be regulated and a signal which is supplied by a current converter (10) which transforms the total current through the electronic switch, characterised thereby, that a unidirectional voltage value, which is proportional to the peak value of the total current through the electronic switch (6) and which is obtained by peak integration of the current converter output signal, serves as signal for the output magnitude to be regulated.
