Jay Baliga, Distinguished University Professor of Electrical and Computer Engineering at NC State and co-author of the paper. “That reduction in resistance means that these devices can handle ten times as much power.”
NC State’s role is to develop a transformerless intelligent power substation (TIPS), says Dr. Subhashish Bhattacharya, an assistant professor of electrical and computer engineering at NC State and primary investigator for the university on the grant project. “TIPS will enable the vision of the smart grid,” Bhattacharya says. “It will be a more cost-effective and efficient means of connecting renewable energy resources to the existing power infrastructure.”
Specifically, Bhattacharya explains, TIPS will enable the direct interconnection of renewable energy resources and energy storage systems to the grid with bidirectional power flow control. It will also provide energy management, and improve grid power quality and reliability through enhanced communication. Dr. Alex Huang, professor of electrical and computer engineering, is a co-primary investigator on the NC State component of the grant.
The paper, “Planar, Nearly Ideal Edge Termination Technique for GaN Devices,” will be published in IEEE’s Electron Device Letters.
The research was supported by NC State’s Future Renewable Electric Energy Delivery and Management Systems Centre, with funding from the National Science Foundation.
US DOE Awards Cree to Develop SiC Power Device
The ARPA-E grant will fund a number of organisations to research smart grid technologies.
A new grant from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) will support North Carolina State University efforts to develop new technologies essential to the development of a “smart grid” that can easily store and distribute energy from renewable sources, such as solar and wind.
The ARPA-E grant is for a total of $5.15 million over three years, the bulk of which will be going to Cree, which is leading the initiative. Partners in the initiative include NC State, ABB and Powerex. NC State will receive $750,000 over the life of the grant.

The NC State TIPS development project will be made possible by the work that Cree will be doing under the grant – developing a power semiconductor device based on silicon carbide.
NC State is recognized as a leader in developing smart grid technologies, and is home to the National Science Foundation’s Engineering Research Centre for Future Renewable Electric Energy Delivery and Management (FREEDM). Headquartered on NC State’s Centennial Campus, the FREEDM Systems Centre is developing ways to speed renewable electric-energy technologies into every home and business.
Defence Semiconductor Market to Maintain Growth
According to Strategy Analytics, revised projections still indicate CAGR of over 6% through 2015.
While trying to save more than $150 billion over the next five years, the US Department of Defence will focus on technology which will translate into continued development on radar, EW (Electronic Warfare), communications and other advanced defence capabilities.
