Abstract
A laminated transformer can include: a plurality of magnetic layers; a plurality of coil layers including a primary coil having a first type of coil layer, and a secondary coil having a second type of coil layer, where each coil layer is laminated between a pair of the plurality of magnetic layers; and a plurality of non-magnetic layers, where a first of the plurality of non-magnetic layers is disposed between an adjacent pair of the coil layers in order to increase a coupling coefficient between the primary and secondary coils.
