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 5):
The active clamp control circuit of  claim 4 , wherein the timing circuit comprises:\n a) a first comparator halving non-inverting and inverting input terminals; b) a current source, a first capacitor, and a first switch that are connected in parallel between the non-inverting input terminal and a ground, wherein the inverting input terminal is configured to receive a control signal corresponding to the peak value of the inductor current; c) wherein an inverted signal of the first pulse width modulation signal is configured to control an on state of the first switch, such that the current source is configured to charge the first capacitor during a turn-on period of the auxiliary switch, and to discharge the first capacitor during a turn-off period of the auxiliary switch; and d) the first comparator is configured to compare a first voltage across the first capacitor against the control signal, such that a transition occurs when the first voltage rises to the control signal, thereby generating the timing signal.
