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) [1] 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.
