Wolfspeed wins 2016 R&D 100 Award for wide bandgap underhood inverter for HEVs/EVs

Green Car Congress

Underhood inverters convert the DC power stored in hybrid, plug-in hybrid, or all-electric vehicle battery packs to three-phase AC power that can be used to energize one or more electrical loads, and traditionally employ industry standard silicon semiconductors. —John Palmour, Wolfspeed’s chief technology officer.

Lux: future use of wide bandgap materials in power electronics will reduce EV cost

Green Car Congress

They also offer greater efficiency in converting AC to DC power and in operating the electric traction drive during vehicle use. Applied in an EV, WBG materials could cut electricity losses by 66% during vehicle battery recharging, the DOE says. As just one example of government funding, the US DOE is contributing $1.8 million to a $3.8-million
