Inverter transformer
First Claim
1. An inverter transformer comprising a primary winding and a secondary winding which are disposed in side-by-side relationship with each other;
- anda pair of cores disposed in abutting relationship with each other so as to form a closed magnetic path, said primary and secondary windings being electromagnetically coupled to each other through said pair of cores;
at least one of said cores being provided with a protuberance, said protuberance being disposed in opposing relationship to the other core, with an air gap defined therebetween, said protuberance being interposed between said primary and secondary windings, characterized in that;
at least one of said cores comprises a bottom plate and two projections extending perpendicularly from said bottom plate;
said primary winding is provided around one of said projections;
said secondary winding is provided around the other projection; and
a portion of the bottom plate to which said secondary winding opposes is made smaller in terms of thickness than a portion of the bottom plate to which said primary winding opposes.

Abstract
In an inverter transformer comprising a primary winding and secondary winding which are wound on a first and a second spool respectively and disposed in juxtaposing relationship.with each other with the axes of the first and second spools being substantially parallel to each other, and a pair of cores which are disposed in abutting relationship to each other so as to define a closed magnetic path, the primary and secondary windings being electromagnetically coupled to each other through the pair of cores, at least one of said cores being provided with a protuberance which is disposed in opposing relationship to the other core, with a small distance maintained therebetween, the protuberance being interposed between the primary winding and the secondary winding, the arrangement is made such that secondary-side minimum sectional area of that portion of the cores through which magnetic flux is permitted to pass, is given substantially by S1 K, where S1 is primary-side minimum sectional area of that portion of the cores through which magnetic flux is permitted to pass, and K is the electromagnetic coupling coefficient between the primary winding and the secondary winding.
