Abstract:
A controller ( 100 ) for a quasi-resonant (QR) flyback converter ( 200 ) having a switching element ( 210 ) operable at a switching frequency (F) is presented. The controller ( 100 ) is configured for repeatly: receiving, from the QR flyback converter ( 200 ), a controller input signal (ZC); determining a designated point of time at which the controller input signal (ZC) equals a threshold value (V_zcd), the designated point of time depending on a switching operation of the switching element ( 210 ); in response to determining the designated point of time, providing, to the QR flyback converter ( 200 ) and after a time delay, a controller output signal (G) for causing a further switching operation of the switching element ( 210 ); and modifying at least one of the threshold value (V_zcd) and the time delay (DT) by an amount, wherein modifying the at least one of the threshold value (V_zcd) and the time delay (DT) varies periodically, the period (TMF) of the modification period being the inverse of a modification frequency (MF).

Claim (Index 11):
The controller as in  claim 10 , wherein the threshold value (V_zcd) and the time delay (DT) collectively define a point of time of the turn on operation.
