Abstract
Mn-Zn cores are widely used in high-frequency high-power power electronics applications. In order to manage with kilowatt and even higher power ratings large cores are required. In this issue the magnetic cores themself are affected by inherent physical parameters and thus their performances are limited and additional losses are generated. This phenomenon can be summarized as the dimensional effect. It includes eddy current effect and resonance effect. The eddy current effect has been widely discussed but the resonance effect is often neglected. But both effects causes considerable losses in certain sizes and at certain frequencies. Therefore in this paper a review of the existing researches about dimensional resonance effects is presented.
