Abstract :
The relationship of the volume and the weight versus frequency for high-frequency transformers is studied. A complete analytical procedure taking into consideration core loss and winding loss (including eddy current loss) is developed. Analytical and experimental results reveal that higher frequency does result in smaller transformer design but an optimum frequency exists at which a transformer can be designed with the smallest volume and the lowest weight
