State-of-the-Art Technologies for Development of High Frequency Transformers with Advanced Magnetic Materials
With the development of advanced soft magnetic materials of high saturation flux density and low specific core loss and semiconductor power devices, the high frequency transformer (HFT) has received significant attentions in recent years for its widespread emerging applications. The optimal design of high power density HFTs for high performance energy conversion systems, however, is a multiphasic problem that needs special considerations on various aspects such as core material selection, minimization of parasitic components and thermal management. This paper presents a comprehensive review on advancement of soft magnetic materials for high power density magnetic devices and advanced technologies for optimal design of HFTs. The future research and development trends are also discussed.
