Power Electronic Transformer For Smart Grid Application

Abstract

In this paper the control system of Power Electronic Transformer (PET) for the Smart Grid application is proposed. The structure of PET is based on two Cascaded H-bridge (CHB) converters. The electrical energy is transferred between converters using Dual-Active-Bridges (DAB) and high-frequency transformers. This type of coupling has been used to connect the DC-links of all H-bridges. The proposed control system for PET makes it possible for DC-link voltage stabilization and allows to reduce the total harmonic distortion (THD) of converter currents and voltages. The simulation and experimental researches of 600 kVA / 3.3kV PET are presented in the paper.
