Abstract
Solid State Transformers (SSTs) are emerging as the major component of 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 sides of HFT. The most significant among above is the design of magnetic circuit and the possibility of using different magnetic materials for high frequency application. 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. 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 in 1000 kVA 11 kV/415 V SST, is investigated both analytically and numerically, with optimum designs developed using three core materials.
