Patent ID: 7733208

Claim:
A high current DC pulse type transformer for connection to a high pulse current or capacitive discharge type circuit where the transformer is provided with a primary bobbin, a primary winding, a secondary winding frame, a secondary winding barrel, a secondary winding, and a core where: the primary and secondary windings are wound around a common leg of the transformer's core with the primary and secondary windings wound one winding outside the other; the primary winding is wound around said primary bobbin; the peak current through said primary winding is significantly higher than the current necessary to saturate said core; the transformer is a step-up type transformer; the transformer's duty cycle is significantly low; the secondary winding barrel is coaxially around the outside of said primary winding; the secondary winding frame comprises three or more flanges supported longitudinally along one or more flange supports and coaxially around the outside of said secondary winding barrel with said secondary winding barrel exposed between said flanges along part of the secondary winding barrel perimeter in one or more winding bays; the secondary winding is wound around said secondary winding bay barrel and said secondary winding bay flange supports in two or more winding bays; the secondary winding is a high voltage winding provided in two or more winding bays such that the voltage potential across each winding bay is less than output voltage potential of the secondary winding; and where one or more secondary winding bays are provided with an insulated winding bay barrel that physically separates the primary and secondary windings by several thousandths of an inch or less along at least part of the winding barrel's winding perimeter.
