Disclosed herein is a coil component that includes: a first magnetic core extending in the first direction and around which the wires are wound; a second magnetic core having a first wall surface part covering the first magnetic core from one side in the second direction, a second wall surface part covering the first magnetic core from other side in the second direction, and a third wall surface part covering the first magnetic core from one side in the third direction; first and second terminal electrodes connected respectively to one ends of the wires and arranged in the first direction along the first wall surface part; and third and fourth terminal electrodes connected respectively to other ends of the wires and arranged in the first direction along the second wall surface part.

Three-phase interleaved LLC and CLLC resonant converters, with integrated magnetics, are described. In various examples, the primary sides of the phases in the converters rely upon a half-bridge configuration and include resonant networks coupled to each other in delta-connected or common Y-node configurations. The secondary sides of the phases can rely upon a full-bridge configurations and are coupled in parallel. In one example, the transformers of the phases in the converters are integrated into one magnetic core. By changing the interleaving structure between the primary and secondary windings in the transformers, resonant inductors of the phases can also be integrated into the same magnetic core. A multi-layer PCB can be used as the windings for the integrated magnetics.

A power supply circuit includes a printed circuit board (PCB), and a transformer coupled to the PCB. The power supply circuit also includes a first inductor assembly coupled to the PCB and electrically connected to the transformer, and a second inductor assembly coupled to the PCB and electrically connected to the transformer. The first inductor assembly has an inner edge and an opposite outer edge, and the second inductor assembly has an inner edge and an opposite outer edge. The inner edge of the second inductor assembly is spaced apart from the inner edge of the first inductor assembly by a gap. The power supply circuit also includes a first magnetic shunt coupled to the outer edge of the first inductor assembly, and a second magnetic shunt coupled to the outer edge of the second inductor assembly.

An electronic component includes a wire winding wound around a central axis. The wire winding having first and second ends, and first and second terminals are connected to or formed by the first and second ends. The terminals provide electrical contacts for connecting the component into a circuit. The component has a wet press molded body made of a mixture of magnetic and non-magnetic material that is heated and pressed about the wire winding. The wet press molded body leaves at least a portion of the terminals exposed for mounting the component to the circuit.
