The result indicates insignificant differences between the two types of magnetic nonfluids in terms of the magnetic flux distribution inside the fluid part of the magnetic core. However, because of the higher saturation limit, the NMF-UTR40-500G it is expected to perform better in higher power applications. For different models, the numerical investigations was performed under steady state conditions, to estimate the lumped parameters of the transformer and to
