1. A converter comprising:
a magnetic material;
a first circuit configured to convert power received from a first input voltage source to provide the converted power to a load, and to reset an operation of the power converter using a clamp circuit, the first circuit comprising:
a first winding surrounding the magnetic material,
a first main switch connected to the first input voltage source,
a first inductor connected to the first winding, and
the clamp circuit; and
a second circuit configured to convert power received from a second input voltage source to provide the converted power to the load and to perform a power conversion operation being reset by the clamp circuit, wherein the second circuit is a primary side circuit structure of a flyback converter, the second circuit comprising:
a second winding surrounding the magnetic material,
a second main switch connected to the second input voltage source, and
a second inductor connected to the second winding;
wherein the clamp circuit comprises:
a clamp switch connected to the first main switch, and
a clamp capacitor between the clamp switch and the first inductor and connected in series with the clamp switch and the first inductor, wherein the first main switch and the second main switch are configured to be turned on or turned off at a same time, and the clamp switch is configured to operate complementary to the first main switch.
