© 2014 IEEE. Amorphous and nanocrystalline alloys show attractive magnetic properties, and can be the excellent choice to develop the cores of high-frequency high-power transformers used in high-power density renewable power generation systems. However, the electromagnetic design of high-frequency power transformers is a multi-physics problem and thereby affects the system efficiency and cost. In this paper, four high frequency transformers are optimally designed with amorphous and nanocrystalline alloy-based cores and electromagnetic performances are evaluated by finite element method. The results are analyzed and found their huge potentiality for future smart grid applications.
