Power transformers are one of the most important components of power system. It is known that these transformers are the heaviest and most expensive parts in an electrical distribution system. With developing technological innovations, it was proposed a new transformer concept. These new power transformers have been called as electronic power transformer. Many different topologies for PETs are also available in the literature. In this study, EGT structure consisting input, isolation and output stages was carried out in Matlab/Simulink environment. EGT structure consists of the three-phase pulse width modulation (PWM) based rectifier in input stage, the dual active bridge in isolation stage and the three-phase inverter circuit in output stage. Moreover, the results obtained from these stages are given and EGT structure is evaluated in many aspects this study.
