Optimum Circumscribing Circle Division Method for Getting Maximum Fill Factor in Transformer Core

Abstract

As far as the optimum design of transformer is concerned, researchers generally concentrate on minimizing cost, no load and load losses etc. by choosing K-factor, Flux density, Current density etc. as design variables. But, the design of core has remained an unexplored area. Transformer manufacturing industry uses traditional technique to find out the core design dimensions. However, in that method, the fill factor for the desired number of steps is not maximized. The advantages of maximizing the fill factor includes reduced diameter and hence reduced copper material and associated cost and losses, increased efficiency, etc. In this paper, a new method, referred to as Optimum Circumscribing Circle Division Method (OCCDM), is suggested to maximize the fill factor for the desired number of steps in the transformer core.
