Embodiment Construction

[0049] The embodiments described in detail below are particularly suitable for application in isolated boost power converters providing DC voltage amplification or boosting. However, those skilled in the art will understand that the integrated magnetics implementations described below are very useful for other types of applications such as buck power converters and multi-coupled inductors with variable coupling coefficients.

[0050] figure 1An assembled perspective view of the integrated magnetic component 100 according to the first embodiment of the present invention is shown. Integrated magnetics 100 includes a magnetically permeable core 101 having a base member 102 and a top member 104 . The base member 102 includes a first leg 110, a second leg 112, a third leg 114 and a fourth leg 116, all of which protrude substantially perpendicularly from the base member 102 to the lower surface of the top member such that the top member is respectively attached to Opposite ends o...

Abstract

The present invention relates to an integrated magnetic component comprising a magnetically permeable core. The magnetically permeable core comprises a base member extending in a horizontal plane and first, second, third and fourth legs protruding substantially perpendicularly from the base member. First, second, third and fourth output inductor windings are wound around the first, second, third and fourth legs, respectively. A first input conductor of the integrated magnetic component has a first conductor axis and extends in-between the first, second, third and fourth legs to induce a first magnetic flux through a first flux path of the magnetically permeable core. A second input conductor of the integrated magnetic component has a second coil axis extending substantially perpendicularly to the first conductor axis to induce a second magnetic flux through a second flux path of the magnetically permeable core extending substantially orthogonally to the first flux path. Another aspect of the invention relates to a multiple-input isolated power converter comprising the integrated magnetic component.
