Abstract:
A flyback power converter circuit includes: a transformer including a primary side winding coupled to an input power and a secondary side winding coupled to an output node, wherein the input power includes an input voltage; a primary side switch coupled to the primary side winding for controlling the input power to generate an output power on the output node through the secondary side winding, wherein the output power includes an output voltage; a clamping circuit including an auxiliary switch and an auxiliary capacitor connected in series to form an auxiliary branch which is connected with the primary side winding in parallel; and a conversion control circuit for adjusting an ON time of the auxiliary switch according to at least one of a current related signal, the input voltage, and the output voltage, such that the primary side switch is zero voltage switching when turning ON.

Claim (Index 19):
The flyback power converter circuit of  claim 17 , wherein the sequence circuit includes:\n a first sequence control circuit, configured to operably generate the auxiliary switch control signal according to the auxiliary switch start signal and a first timing control signal, wherein the auxiliary switch start signal triggers the auxiliary switch control signal to turn ON the auxiliary switch, and the first timing control signal triggers the auxiliary switch control signal to turn OFF the auxiliary switch; a first timing control circuit, configured to operably generate the first timing control signal according to the auxiliary switch start signal to determine the ON time of the auxiliary switch; a second timing control circuit, configured to generate a second timing control signal according to the first timing control signal to determine the auxiliary dead time, wherein both the primary side switch and the auxiliary switch are OFF during the auxiliary dead time; a second sequence control circuit, configured to operably generate the primary side switch control signal according to the second timing control signal and a third timing control signal, wherein the second timing control signal triggers the primary side switch control signal to turn ON the primary side switch, and the third timing control signal triggers the primary side switch control signal to turn OFF the primary side switch; and a third timing control circuit, configured to operably generate the third timing control signal according to the second timing control signal to determine an ON time of the primary side switch.
