Lightweight Transformer

Abstract

The creation of the Strategic Defense Initiative Organization (SDIO) in 1983 has established a challenge to the technical community to provide the required science and engineering necessary to achieve the objectives of the SDIO. This technical challenge is present in the requirements for minimum mass, high performance power conditioning systems capable of achieving the space-based SDIO mission applications. Transformers and their related structure are major components of the power conditioning systems for many of the SDIO mission aigned during this program is a liquid hydrogen cooled air core transformer that uses thin copper for its primary and secondary windings. The transformer winding mass was approximately 12 kg, or 0.03 kg/kW. Further refinements of the design to a partial air core transformer could potentially reduce the winding mass to as low as 4 or 5 kg, or 0.0125 kg/kW. No attempt was made on this program to reduce the mass of the related structural components or cryogenic container. transformer. Based on the results obtained, this transformer technology shows promise for substantially reducing the transformer mass, and further development and refinement of this concept should be pursued.
