"Today, Google and the IEEE are proud to announce that the grand prize winner of the $1 Million Little Box Challenge is CE+T Power’s Red Electrical Devils."

Google Research Blog: The Red Electrical Devils (named after Belgium’s national soccer team) were declared the winner by a consensus of judges from Google, IEEE Power Electronics Society and NREL. by Ross Koningstein

'Honorable mentions go to teams from Schneider Electric and Virginia Tech’s Future Energy Electronics Center. Schneider, Virginia Tech and The Red Electrical Devils all built 2kW inverters that passed 100 hours of testing at NREL, adhered to the technical specifications of the competition, and were recognized today in a ceremony at the ARPA-E Energy Innovation Summit in Washington, DC. Among the 3 finalists, the Red Electric Devils’ inverter had the highest power density and smallest volume.

'Impressively, the winning team exceeded the power density goal for the competition by a factor of 3, which is more than 10 times more compact than commercially available inverters! When we initially brainstormed technical targets for the Little Box Challenge, some of us at Google didn’t think such audacious goals could be achieved. Three teams from around the world proved decisively that it could be done.

'As a condition of entering the competition, all teams agreed to have their technical approach documents, describing how they built their inverters, made public. We post links to the technical approach documents of the 18 finalists selected for testing at NREL here in order to recognize their achievements and in hopes of furthering the state of the art in power electronics.'
