The Power Electronics and Electric Machinery Research Group is located at the National Transportation Research Center (NTRC) and is approximately halfway between Oak Ridge National Laboratory, in Oak Ridge, and The University of Tennessee, in Knoxville. 

The NTRC has more than 9,000 square feet of space for developing, building, and testing the next-generation prototype power electronics and electric machine technologies. Staff members use and develop the latest analysis, simulation, and modeling software to develop designs prior to hardware implementation. For more information on the NTRC, please see visiting us.
