Characterisation of Amorphous Metal Materials for High-Frequency High-Power-Density Transformer

摘要

In many applications such as power electronic devices, it is very desirable to employ high power-density transformers, because the available space and allowed weight are very limited. In general, operating at higher frequency would lead to smaller volume and weight of electromagnetic devices, but the core loss could increase significantly. With very low specific core loss and relatively high saturation magnetic flux density, amorphous metal (AM) materials offer great potential. This scientific research aims to study and model the AM properties for developing high performance transformers such as high efficiency and high power density. The use of Amorphous metals as a core material enables high frequency transformers to attain optimum and higher level of efficiencies. This scientific paper discusses: (i) theoretical understanding of the process of magnetisation and a discussion of AM magnetic properties as are useful for design of electrical devices (ii). Characterize the AM materials and to distinguish them on the basis of their distinctive magnetic properties and their usefulness for High frequency High Power Density (HFHPD) Transformers.
