ABSTRACT:
The present invention provides a high voltage, step-up, high current DC pulse type transformer with increased coupling coefficient between the primary and secondary windings through close proximity of the primary winding turns and secondary winding turns by means of transformer construction that provides a plurality of winding bays for a high voltage secondary winding physically located in close proximity to the primary winding. The plurality of winding bays for the secondary winding are provided by means of a frame and separate thin insulation layer where the thin insulation layer provides the barrel for all or part of the secondary winding. The invention significantly increases the transformer's coupling coefficient in high voltage step-up transformer applications where the transformer's core is pushed beyond saturation due to the high peak current typically found in capacitive discharge type circuits such as those used in electric fence controllers, strobe circuits, and high performance ignition systems for automobile, marine, or motorcycle engines.
