Analysis of orthogonal-core type transformer for DC-AC interconnection system

This paper presents the quantitative analysis of the orthogonal-core type transformer used in a converter for dc-ac interconnection system. The power versus phase angle relation of the transformer is calculated by using the flux-MMF relationships of the orthogonal-core. The analytical results agree well with the experimental ones. The analysis presented here is useful for development of the dc-ac interconnection system.
