Claim:
A three-phase line reactor apparatus, comprising: a core structure, comprising: a top yoke structure having first, second and third ends spaced from one another and from a top yoke structure center in a common top horizontal plane, the first, second and third ends being horizontally non-coplanar, a bottom yoke structure having first, second, and third ends spaced from one another and from a bottom yoke structure center in a common bottom horizontal plane, the first, second, and third ends of the bottom yoke structure being horizontally non-coplanar and generally vertically aligned with the first, second, and third ends of the top yoke structure, a first core leg structure extending between the first end of the top yoke structure and the first end of the bottom yoke structure, a second core leg structure extending between the second end of the top yoke structure and the second end of the bottom yoke structure, and a third core leg structure extending between the third end of the top yoke structure and the third end of the bottom yoke structure; a first winding formed at least partially around the first core leg structure; a second winding formed at least partially around the second core leg structure; and a third winding formed at least partially around the third core leg structure; wherein at least one of the top yoke structure and the bottom yoke structure comprise three yoke portions, each yoke portion having a first end forming part of one of the yoke structure ends, a center, and a second end forming part of another one of the yoke structure ends; wherein each yoke portion is a laminated structure; and wherein each yoke portion comprises two sets of angled laminations, with the center of each yoke portion including interleaved ends of the two sets of angled laminations.
