Distribution systems equipped with power electronic transformers

The paper's aim is to analyze a power electronic transformer (PET) able to deal with different sources at its input port, being able to distribute, according to the system's strategies, where the power comes from. Thus, the multi-fed PET (MF-PET), is a power electronic transformer with two or more AC/DC rectifiers in its input port, and these may be connected to different feeders. High service quality to consumers is accomplished. Simulating results for the three-phase topology are shown operating as an electronic device and as part of a grid. A fuzzy controller is proposed to coordinate its behavior. Different events are simulated.
