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.
