Abstract

See full text

A semiconductor transformer provides high frequency operation by forming the primary windings of the transformer around a section of magnetic material that has a hard axis that lies substantially parallel to the direction of the magnetic field generated by the primary windings. The core can also be formed to have a number of sections where the magnetic flux follows the hard axis through each section of the core.
