SPEC delivers advanced SiC power converters to Oak Ridge National Laboratory (ORNL)

Dec 2022: SPEC has successfully completed a two-year project sponsored by the Department of Energy’s Office of Electricity’s (OE), Transformer Resilience and Advanced Components (TRAC) program and Oak Ridge National Laboratory (ORNL). The project is led by Dr. Alex Huang, SPEC center director and ECE professor, with major contributions from Zibo Chen, Chen Chen, Houshang Salimian, and Rahul Choudhary. The project resulted in the delivery of two ready-to-operate SiC converters for ORNL. The high-power density 75kVA air-cooled SiC intelligent power stage (IPS) serves as a standardized plug-and-play universal building block for various grid-connected renewable energy applications. Hence the developed IPS can provide an opportunity to simplify renewable energy integration and increase the grid’s resilience, efficiency, and flexibility.

SPEC ECCE 2022

IEEE ECCE 2022

Oct 2022: Professor Alex Huang and several researchers from the Semiconductor Power Electronics Center (SPEC) attended the 2022 IEEE ECCE Conference in Detroit, Michigan from 10/09/2022 to 10/13/2022. Dr. Huang also served as a panelist in a special session on the Challenges and Potential of " Standard Development for Solid State Transformer: An Update On Existing IEEE Standards On Magnetics And New Standard for Solid State Transformer ". Furthermore, he was the chair of the session on " Multi-Level and Multi-Phase Converters". Eight papers from Dr. Huang’s group were presented at this conference.
