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 10):
The conversion control circuit of  claim 9 , wherein an ON time of the auxiliary switch increases according to at least one of the followings: (1) when the current related signal indicates that a peak current of the primary side switch is decreasing, (2) when the input voltage is increasing, and/or (3) when the output voltage is increasing, such that the auxiliary switch conducts a magnetizing current of a parasitic magnetizing inductance of the primary side winding to discharge a parasitic capacitor of the primary side switch, whereby the primary side switch is zero voltage switching when the primary side switch turns ON.
