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 3):
The active clamp control circuit of  claim 1 , wherein the active clamp control circuit comprises a first circuit configured to provide a first drive signal to the auxiliary switch, the first circuit comprising:\n a) a first set signal generating circuit configured to generate a first set signal according to a first pulse width modulation signal; b) a first reset signal generating circuit configured to generating a first reset signal according to the peak value of the inductor current; c) a first logic circuit configured to generate the first pulse width modulation signal according to the first set signal and the first reset signal; and d) a first drive circuit configured to generate the first drive signal according to the first pulse width modulation signal, wherein the first set signal and the first reset signal respectively characterize a turn-on time and a turn-off time of the auxiliary switch in the switching period, the first time period is a time period between the continuous turn-on time and the turn-off time in the corresponding switching period, and the first time period is adjusted by the first circuit according to the peak value of the inductor current.
