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.
