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 10):
The active clamp control circuit of  claim 9 , wherein the peak value detection circuit comprises:\n a) a peak current setting circuit configured to generate a current reference signal according to the detection signal of the direct current output voltage of the flyback converter to set the reference current; b) a rising edge blanking circuit configured to delay a predetermined blanking time for the detection signal of the inductor current; and c) a second comparator configured to compare the detection signal of the inductor current with the current reference signal, such that a transition occurs when the inductor current rises to the reference current, thereby generating the trigger signal.
