ABSTRACT:
A transformer core is disclosed having one or more winding legs built up from a plurality of silicon steel laminations and a pair of yokes built up from a plurality of amorphous steel laminations. The yokes and legs are serially joined by silicon steel-amorphous steel lamination joints to create a magnetic loop circuit and thus provide a transformer core having significantly improved core loss characteristics as compared to a power transformer core formed exclusively of silicon steel laminations.
