The object of the proposed program is to demonstrate feasibility of designing high efficiency transformers of low mechanical profile for high frequency power conversion applications. The program will be directed toward gaining insight into the dominant loss mechanisms of the winding and core structures at high frequencies. New approaches for transformer construction, such as the use of laminated ferrite materials will be investigated, as well as using air core construction in order to reduce core losses. A family of parametric performance characteristics will be developed to guide the optimization process. Windings will be fabricated using advanced photolithography, etching and plating processes. High speed automatic dicing saws will be used to fabricate magnetic cores.
