Abstract:
A flyback power converter circuit converting an input voltage to an output voltage includes a transformer, a power switch, a synchronous rectifier (SR) switch, and a secondary side control circuit. The secondary side control circuit controls the SR switch to be ON when the power switch is OFF. The secondary side control circuit includes a driving switch for controlling the SR switch, a synchronous control circuit powered by a voltage related to the output voltage, which controls the driving switch to operate the SR switch, and a clamping circuit including a clamping switch and a clamping switch control circuit. The clamping switch control circuit controls the clamping switch according to a current inflow terminal voltage of the clamping switch and/or the voltage related to the output voltage, such that, during a secondary side power-on period, an equivalent impedance of the current inflow terminal of the clamping switch is smaller than a predetermined clamping impedance.

Claim (Index 30):
The secondary control circuit of  claim 21 , wherein the clamping switch control circuit further includes a reverse blocking diode which is coupled in series between the control terminal of the clamping switch and one of the clamping resistor, the clamping current source circuit, or the impedance control switch, and is configured to operably block a reverse current, wherein a current outflow terminal of the reverse blocking diode is electrically connected to the control terminal of the clamping switch.
