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 9):
The controller as in  claim 1 , wherein the controller output signal (G) is a switch signal for the switching element, and wherein the controller is operable to alter the switching frequency (F) based on the modifying of the at least one of the threshold value (V_zcd) and the time delay (DT).
