Abstract: A multi-coil inductor includes a plurality of stacked inductor units. Each of the inductor units comprises: a magnetic core in which a magnetic path is formed; and a plurality of coils which are wound around the magnetic core to form at least one winding pair. Wherein a part of the magnetic path between the adjacent inductor units is shared. In the present invention, the leakage inductance is controlled and the maybe magnetic saturation of magnetic core avoided by adjusting series and parallel connections among the coils.

Abstract: An isolated resonant converter is provided, including a first side circuit, a second side circuit, and a resonant tank circuit. The resonant tank circuit includes a first resonant capacitor, a second resonant capacitor, and an integrated magnetic element. The integrated magnetic element includes a first side winding, a second side winding and a spaced groove provided between the first side winding and the second side winding. And the spaced groove stores leakage inductance energy, thereby forming at least part of resonant inductance required. Therefore, a number and volume of magnetic elements in the resonant converter are reduced.
