Abstract
An inverter transformer is formed of first and second cores arranged to face each other to form a closed magnetic circuit. The first core has a central leg, an outer perimeter wall, and a partition between the central leg and the outer perimeter wall so that a first groove is formed between the central leg and the partition and a second groove is formed between the partition and the outer perimeter wall concentrically with and outside the first groove. A primary winding is disposed in the second groove, and a secondary winding is disposed in the first groove so that the primary and secondary windings are arranged in the same plane.
