Abstract
Disclosed is an electrical transformer for improved transformer power capacity and efficiency designed by the application of disclosed design considerations. One embodiment design consideration is a method to configure power transformer windings wherein the minimum distance of the primary windings from the winding axis/core center is greater (the primary windings are more distal) from the winding axis than the minimum distance of the secondary windings, which are wound around the minimum interior core diameter. This design consideration is extended from single bobbin transformer designs to split bobbin designs, with the requisite distal increase of the primary windings (from the core axis) geometrically provided by an enlarged core bobbin center leg (axial) dimension beneath the primary winding window. Another disclosed design consideration is to fix the primary winding length relationship to the core weight for given transformer specifications in accordance with the disclosed unexpected experimental results and formula.
