ABSTRACT:
The invention concerns a control circuit (20) of a switch (6) chopping a voltage supply of a primary winding of a power converter transformer, comprising means (45) for detecting the current in the switch in closed state after a predetermined time following each closure of said switch, and a comparator (40) of said current relative to a threshold (Ilim), the result of said comparator being taken into account for a predetermined time interval close to the beginning of a closing cycle of said chopping switch.
