| Abstract |
An efficient, meanwhile simple optimization routine is presented for design of high frequency power
transformers. Minimizing the product of power loss, core cross section and winding area is chosen as
the optimization goal. This object function leads to a closed form solution, which reduces the
computation time and the number of iterations. A CAD tool has been developed according to this
method, which is addressed in this paper. By this tool the optimized core which fulfills the
temperature rise constraint is determined. If the area product of the selected core is bigger than the
optimum area product, the user can modify his design further by minimizing the power loss. The
validation of the method is verified by a sample design example. |
