Characterization of the Optimized High Frequency Transformer Using Nanocrystalline and Amorphous Magnetic Materials
2019 IEEE. High frequency transformers (HFTs) suffer from high core loss because of high operating frequencies and low magnetic flux saturation of core materials. Latest soft-magnetic materials having the properties of higher flux density, low core loss at medium or high frequencies and high electrical resistivity greatly contribute to the solution of high core losses of HFTs. In this paper, a toroidal core HFT is optimized using human intervened genetic algorithm, mathematically modeled, and characterized in terms of low core loss, better load-power characteristics, and higher efficiency as well as amorphous and nanocrystalline magnetic materials are compared based on their electromagnetic properties. It is nominated that the characterization will lead significant role in the development of next generation HFTs.
