N2 - The availability of improved magnetic materials and higher voltage rating semiconductor devices have made the design of high power medium frequency transformers feasible. The paper presents a simple design procedure to determine the core dimensions based on the area product method. A winding design procedure to use foil conductors in the high voltage side to achieve ac-to-dc resistance ratio close to 1 is also shown, providing a possible replacement to the litz wires having low window utilization factor. The paper demonstrates a design example of 13.8kV/690V, 10kHz, 50kVA transformer to validate the design methodology and the winding losses are validated using 2-D FEM.
