ELECTRONICS AND ELECTRIC MACHINERY RESEARCH CENTER |
 |
The
U.S. Department of Energy’s broad-based research center for power electronics
and electric machinery and associated technologies is located at the NTRC.
Researchers in the Power Electronic and Electronic Machinery Research Center
develop and prototype the next generation of cost-effective converters,
adjustable-speed drives, electric utility and distributed-generation applications,
motor controls, and efficient, compact electric machines. |

Facilities
and Equipment
The laboratory
area of the ORNL Power Electronics and Electric Machinery Research Center
has more than 700 m2 (9000 ft2) of space for developing and building the
next-generation prototypes of inverters, rectifiers, and electric machine
technology. Team members use and develop the latest analysis, simulation,
and design software to provide proof of principle before hardware implementation
of their circuit and motor designs.
