Power electronic transformer based on AC voltage regulator

Power electronic transformers (PET) based on ac voltage regulator with pulse-width regulation, in various areas of their application are discussed. A research of a power electronic transformer based on an ac voltage regulator operating at high frequency with ability to support unity power factor by means of mathematical modeling is conducted. The major power characteristics are obtained using the output factors of electric energy quality of the device. A universal single-phase experimental mock-up is presented.
