Abstract :
A converter system based on medium frequency dc/dc-converters can replace the conventional traction transformer saving both mass and energy. A medium-frequency-transformer design-procedure is introduced that allows a clear representation of transformers total mass and efficiency under consideration of thermal aspects. measurements with a prototyped mf-transformer verify the calculated results.
