  • Abstract
    An examination is made of the important loss aspects of the design of co-axial winding transformers such as the influence of skin effect on winding resistance, the variation of the core loss caused by nonuniform core flux density, and the choice of the principle dimensions and aspect ratios for maximum efficiency. Experimental measurements on a 50 kVA 50 kHz unit are included to confirm portions of the analytical results and suggested design procedures.<>
