A new method to analyse eddy current loss in an integrated magnetic structure for boost converter

This paper proposes a new integrated structure for the interleaved boost converter. The structure includes the main windings and the multipliers on the same core. Where the single core boost topology would provide a minimum iron losses. A new method to calculate the eddy current loss for the used core is presented. The method takes into consideration the effect of the harmonics at different duty cycles on the eddy current and hysteresis losses in the core. A prototype was build and test was carried out to verify the performance.
