| 摘要 |
The invention proposes a method for operating an actively clocked PFC circuit (2) having a directly or indirectly connected load circuit (5) at the output of the PFC circuit (2), wherein the load circuit (5) has at least one luminous means, in particular one or more LEDs (4), wherein the PFC circuit (2) is controlled by a PFC controller (30) in such a manner that the PFC controller (30) determines a control parameter, in particular a switched-on time period (ton), for the clocking of the PFC circuit (2) on the basis of at least one first controller setting (RE_fast) and one second controller setting (RE_slow), wherein the time of a change from the first controller setting (RE_fast) to the second controller setting (RE_slow) is dependent on the directly or indirectly determined average value of the control parameter, in particular the switched-on time period (ton). |
