Fundamental Operation of Orthogonal-flux Type Transformer for DC-AC Interconnection System

Abstract

This paper describes the fundamental operation of the orthogonal-flux type transformer for DC-AC interconnection systems. The power conversion of the orthogonal-flux type transformer is calculated by using the flux-MMF relationships of the orthogonal core, and the calculated values agree well with the experimenal ones. The analytical results obtained here are useful for designing an DC-AC interconnection system which incorporates the orthoeonal-flux type transformer.
