Abstract

A new low profile, light weight, high power density and high efficiency planar transformer for aerospace application is presented. In this paper, a systematic optimizing procedure is illustrated with a detailed design of a flyback transformer. We use double 2D finite element method (FEM) modeling strategies to calculate the power loss and to optimize the design. The strategies, interleaving and horizontal and vertical parallel windings for reducing the winding loss are discussed. A 6-layer PCB layout is shown to validate the design.
