Characterization of a High Power Nanocrystalline Transformer

Summary form only given. Nano-crystalline ferro-magnetic core material has very favorable magnetic properties for high frequency power applications. This paper investigates the properties of a nanocrystalline transformer with multiple secondary windings through experimental evaluation over a range of frequencies. Design considerations are addressed with special attention focused on scaling with respect to frequency, leakage inductance, and effective AC resistance of the windings. The data derived from the experimental evaluation yields scaling factors to help determine a transformer design for optimal power density.
