Multiphysics Analysis of High Frequency Transformers Used in SST with Different Magnetic Materials

Year: 2023

Type: article

Abstract: Solid State Transformers (SSTs) are emerging as the major component of a smart grid system.High Frequency Transformer (HFT) is the key element of SST.The optimum design of SST is a critical task due to the complex design of magnetic, electric, and dielectric circuits of high frequency transformer and due to the design of power electronic circuits used at either side of HFT.The most significant among the above is the design of the magnetic circuit and the possibility of using different magnetic materials for high frequency applications.This paper discusses the performance analysis of HFT for different magnetic materials used for core construction.The magnetic materials considered in this analysis are amorphous, nanocrystalline, and si-steel.The optimum HFT design is selected from a set of designs using an iterative algorithm, considering each core material separately.Validation of the design is done in Finite Element Method (FEM) analysis software.The design of a high frequency transformer, which is integrated with 1000 kVA 11 kV/415 V SST, is investigated both analytically and numerically, with optimum designs developed using three core materials.
