Abstract – This paper analyzed the power loss of transformers considering the magnetic component.
For this, each winding strategy and the effect of air gap between the ferrite core have been an
important variable for optimal parameter calculation. Inductors are very well known design rules to
devise, but the performance of the flyback converter as a function of transformer winding strategy has
not been fully developed. The transformer analysis tool used was PExpert. The influence of the
insulator thickness, effect of the air gap, how the window height and variation of the capacitive value
effects the coil and insulator materials are some of parameters that have been analyzed in this work.
The parameter analysis is calculated to a high frequency of 48[kHz]. Therefore, the final goal of this
paper was to calculate and adjust the parameters according to the method of winding array and air gap
minimizing the power loss
