چکیده مقاله :

In order to reduce the volume and size of distribution power transformer, precise and extended controlling of transformer output, the conventional transformers are replaced by intelligent universal transformers (IUTs). In this paper, an IUT, typical of Iran national grid, with the voltage ratio of 20kV:380 V is designed and simulated. Regarding the IUT implementation, a cascaded H-bridge inverter (CHB), and a double active bridge (DAB) inverter, along with a three-phase inverter is used. Finally, the proposed IUT is simulated in various conditions
