Abstract: Methods and systems useful in reducing leakage inductance in a flyback transformer. By way of example, a flyback transformer includes a bobbin. The flyback transformer includes primary windings and secondary windings configured to enter a first side of the flyback transformer, to wrap around the bobbin of the flyback transformer to form a bifilar coil or a multifilar coil, and to exit the flyback transformer on the first side of the flyback transformer.
