Design of laboratory model for demonstration of solid state transformer for smart grid applications

摘要

Solid state transformer (SST) is an alternative concept of traditional line frequency transformer in the distribution circuits. It has expedience such as small volume, less weight, high power density, controlled power factor etc. It is very beneficial for future power system. This paper encompasses the system design and demonstration of a high voltage SST laboratory prototype model for smart grid applications. The high voltage high frequency 5KVA SST operating at 3 kHz designs are the prime segments of the system, including power stage are highlighted. Transformers magnetic core materials are compare and selected. The high voltage high frequency 5KVA, 3 KHz transformer prototype are designed and integrate with load.
