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 7):
The active clamp control circuit of  claim 6 , wherein the clamp circuit comprises:\n a) a third comparator connected as a voltage follower, wherein a non-inverting input terminal of the third comparator is configured to receive the control signal of the peak value of the inductor current, and an output terminal is connected to the inverting input terminal; b) a fourth comparator having an inverting input terminal connected to the non-inverting input terminal of the first comparator, and a non-inverting input terminal configured to receive the reference voltage; and c) a clamp switch having a control terminal is connected to an output terminal of the fourth comparator, a first terminal connected to the inverting input terminal of the first comparator, and a second terminal connected to a non-inverting input terminal of its own, wherein when the control signal of the peak value of the inductor current is greater than or equal to the reference voltage, the clamp switch is turned off, and when the control signal of the peak value of the inductor current is less than the reference voltage, the clamp switch is turned on.
