According to one configuration, a fabricator receives magnetic permeable material and fabricates an apparatus to include a multi-dimensional arrangement of electrically conductive paths to extend through the magnetic permeable material. Each of the electrically conductive paths is a respective inductive path.

An inductor element includes a first conductive portion, a second conductive portion, and a magnetic core. The first conductive portion includes a first round-about portion, a first mount portion, and a second mount portion. The second conductive portion includes a second round-about portion, a third mount portion, and a fourth mount portion. The magnetic core houses at least a part of the first and second conductive portions so that each mount surface of the first to fourth mount portions is exposed from one side of the magnetic core. The first and second conductive portions are arranged so that the first and second directions are substantially parallel and opposite to each other. The first and third mount portions are at least partially overlapped with each other in a third direction perpendicular to the first and second directions.

A reactor includes: an outer peripheral iron core; three leg iron cores; and three coils, each of the coils having an input side coil end and an output side coil end projecting from a same end surface on an end side in the axial direction of the three leg iron cores, where the three coils include two first coils in which a projecting position of the input side coil end and a projecting position of the output side coil end has a first relative positional relationship and include one second coil having a second relative positional relationship opposite to the first relative positional relationship and where winding directions from the input side coil end to the output side coil end of the first and the second coils are reversed to each other.

A magnetic component includes a main magnetic core, a power winding coupled to the main magnetic core, a variable reluctance core element arranged in a flux path of the main magnetic core and including a saturable magnetic core and a control winding coupled to the saturable magnetic core. The control winding is isolated relative to the power winding and configured to selectively saturate a section of the saturable magnetic core.

Magnetic core assemblies include a skewing feature that introduces transverse components into the power flux density vector are disclosed herein. A magnetic core assembly comprises a lower core having a center section and an upper core having a center section. The center sections are aligned to form a center post. A power winding that receives current is wrapped around the center post. The core assembly further comprises a power flux density vector that has transverse and non-transverse components. The transverse components have a higher magnetic reluctance than the non-transverse components. When the assembly is used with a transverse winding, the transverse components from the magnetic core assembly produce a transverse voltage waveform on the transverse winding. The transverse voltage waveform may be observed to detect a change in the sign of the slope of the transverse voltage waveform. The change in the sign of the slope indicates magnetic saturation.
