1. A flyback converter system comprising:
a transformer system having a magnetic core; and
a flyback converter circuitry having a primary circuitry and a secondary circuitry,
wherein the flyback converter circuitry is electrically coupled to the transformer system,
wherein the flyback converter circuitry is configured to recycle energy from a leakage flux via the primary circuitry and to transfer the energy to the secondary circuitry, and
wherein the magnetic core comprises a first magnetic core portion and a second magnetic core portion stacked in a vertical configuration, and wherein each of the first magnetic core portion and the second magnetic core portion has a circumference spanning less than 360 degrees, such that an air gap is formed in the magnetic core.
