Abstract:
An active clamp control circuit for a flyback converter can be configured to: control turn-on states of a main switch and an auxiliary switch to make the auxiliary switch turn on for a first time period in at least one switching period, and to make the main switch turn on for a second time period in each switching period, where the first and second time periods are non-overlapping periods of the switching period; and compare a peak value of an inductor current flowing through the main switch against a first threshold to adjust the first time period of the auxiliary switch when the peak value of the inductor current is greater than or equal to the first threshold, such that the first time period is directly proportional to the peak value of the inductor current.

Claim (Index 15):
The method of  claim 14 , wherein the adjusting the first time period of the auxiliary switch comprises:\n a) comparing the peak value of the inductor current against the second threshold that is less than the first threshold; b) adjusting the first time period of the auxiliary switch when the peak value of the inductor current is greater than or equal to the second threshold and less than the first threshold, in order to make the first time period a constant time; and c) adjusting the first time period of the auxiliary switch when the peak value of the inductor is less than the second threshold such that the auxiliary switch turned on for a fixed time by intervals of a plurality of switching periods and maintained a turn-off state during the plurality of switching periods.
