Abstract-The emergence of wide bandgap power semiconductor devices has opened the possibilities of improved electrical performance and power density. Advanced research into wide bandgap power electronics also includes advances in integrated circuit design, semiconductor device modeling, 3D electronic packaging, and computer-aided design of wide bandgap based electronics. These emerging trends are described along with some early results indicating the additional improvements possible in power density. Operation at extreme temperatures also becomes more feasible.Index Terms-Gallium nitride, power integrated circuits, power semiconductor devices, power electronics, silicon carbide, wide bandgap semiconductors.
