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 19):
The method of  claim 16 , wherein the controlling the main switch to be turned on for a second time period in each switching period comprises:\n a) generating a second set signal according to an inverted signal of the first pulse width modulation signal; b) generating a second reset signal according to the detection signal of the inductor current and a detection signal of a direct current output voltage of the flyback converter; c) generating a second pulse width modulation signal according to the second set signal and the second reset signal; d) generating a second drive signal according to the second pulse width modulation signal, wherein the second set signal and the second reset signal respectively characterize the turn-on time and the turn-off time of the main switch in the switching period, and the second time period is a time period between the continuous turn-on time and the turn-off time in the corresponding switching period; and e) generating a trigger signal when the inductor current rises to a reference current, in order to control the second time period.
