Abstract

See full text

A magnetic assembly includes a single bobbin structure that supports a first coil and a second coil. A first E-core has a center leg positioned within the first coil. A second E-core has a center leg positioned within the second coil. An I-core is positioned between the first E-core and the second E-core. The I-core completes a first set of magnetic paths between the center leg and outer legs of the first E-core and also completes a second set of magnetic paths between the center leg and outer legs of the second E-core. The two E-cores and the I-core are stacked in a vertical E-I-E configuration with respect to a common set of pin rails. In one embodiment, the first coil and the first E-core are configured as a transformer; and the second coil and the second E-core are configured as an inductor.
