Abstract
System and method via which a switching element is switched in a regulated state of a switching converter at a predetermined stable switching frequency, wherein a switch-on point of the switching element is predetermined by a switching signal generated via a sawtooth signal reaching/exceeding a switch-on threshold value such that the switch-on point of the switching element falls in a valley of an oscillating voltage prevailing at the switched-off switching element, where a prevailing period duration of the switching signal is continuously determined to detect the period duration that is compared with a predetermined reference period duration of a period duration reference unit, a control variable is generated from the comparison and a gap is changed between the sawtooth signal, which is influenced with the valley-identifying signal, and the switch-on threshold value until ascertaining, with reference to the determined prevailing period duration, the stable switching frequency has been reached.
