ARPA-E awards $30M to 21 projects advance new class of high-performance power converters

Green Car Congress

CIRCUITS project teams will accelerate the development and deployment of a new class of efficient, lightweight, and reliable power converters, based on wide-bandgap (WBG) semiconductors. If successful, the team will construct a 500 kW building block for a DC fast charger that is at least four times the power density of todays installed units.
