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 inner-most 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.
