Abstract :
Legacy transformers are passive, bulky, becoming expensive, and take longer time to deliver. They cannot provide the power quality or control which today´s loads demand for proper functioning and the electric system needs for its survivability. Solid-state transformers have been promising technologies in recent years. EPRI is pursuing development of an innovative solution - the UTtrade (Intelligent Universal Transformer), based on R&D100 Award winner SGTO devices, advanced thermal- management technology and packaging concepts to provide flexible, precise quality and reliable power at affordable costs. The IUTtrade is a multi-function programmable power processing device ideal for Smart Grid and Sustainable Energy initiatives. This paper describes the design and application of this device.
