STEM: Update!

Wide bandgap power electronics devices reduce component size, increase efficiency, and improve performance for hybrid and all-electric vehicles. DC-Link Capacitor and Bus Bar Temperatures. Graphic created by Gilbert Moreno, NREL. Present-day silicon-based traction drive inverters for electric-drive vehicle (EDV) applications require two separate radiators and thermal management systems for the electric-drive components and the conventional internal combustion engine (ICE). This added weight, bulk, complexity, cost, and lack of efficiency is one hurdle to widespread consumer adoption of hybrid electric (HEV) and plug-in hybrid electric (PHEV) vehicles in a competitive market dominated by ICE vehicles. Wide bandgap (WBG)-based components, incorporating devices made from materials such as silicon carbide (SiC), can reduce power electronics component size and potentially reduc...
