'Prototype inverter. Click to enlarge. Using 3-D printing and novel silicon carbide (SiC) wide band gap (WBG) semiconductors, researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) have created a prototype power inverter for electric vehicles that achieves a much higher power density than currently available along with a significant reduction in weight and volume—almost meeting, and in terms of efficiency, beating, DOE’s 2020 targets.
