  author={François Forest and Eric Labour{\'e} and T. Meynard and Mohand Arab},
  journal={IEEE Transactions on Power Electronics},
An analytic formulation dedicated to the design of high-frequency power transformers is presented. This approach is based on the area product, and homothetic core shapes are considered. The temperature increase of the transformer is one of the main input data. Winding losses including the effect of eddy currents are calculated as well as core losses. An original model of magnetic losses valid over a wide frequency range of the common ferrite materials is introduced. The analytic formulation is… CONTINUE READING
