Abstract: A transformer is provided having a stacked core with a pair of outer legs extending between a pair of yokes. The core is arranged in a plurality of layers. Each of the layers includes a pair of yoke plates and a pair of outer leg plates. In an innermost layer, the width of each yoke plate is less than the width of each outer leg plate. In each of the layers, the inner points of the outer leg plates are substantially in contact with the yoke plates. The cross-section of the inner leg and the outer legs may be rectangular or cruciform.

Abstract: The present invention is directed to a method of making a transformer having a stacked core, which includes top and bottom yokes and first and second outer legs. The core also includes an inner leg that is formed from a pair of stacked plates, which abut each along a seam that extends in the longitudinal direction of the inner leg. Each of the upper and lower yokes may be formed from a single stack of plates, or a plurality of stacks of plates. Each of the inner and outer legs may also be formed from a single stack of plates, or a plurality of stacks of plates. The cross-section of the core may be rectangular or cruciform.

Abstract: A coil for a transformer includes first and second coil segments with each coil segment being defined by successive layers of wound conductor sheeting. The coil segments are electrically connected together and are adjacent, defining a space there-between. A plurality of cooling duct pairs are disposed between certain of the layers in each of the first and second coil segments such that, for each cooling duct pair, an end of a cooling duct disposed in the first coil segment is adjacent to an end of a cooling duct disposed in the second coil segment, with the ends being disposed in the space. A connector connects the adjacent ends of each pair of cooling ducts.
