SiC & GaN Power Semiconductors Accelerate Penetration in EVs and Renewable Energy Systems

Silicon carbide (SiC) and gallium nitride (GaN) power semiconductors are gaining mainstream traction in 2026, as electric vehicle (EV) makers and renewable energy developers prioritize efficiency and range. SiC MOSFETs now account for over 40% of new EV onboard charger (OBC) designs, reducing power losses by up to 30% compared to traditional silicon IGBTs. 

In solar inverters and energy storage systems, GaN-based ICs enable higher switching frequencies and compact form factors, lowering system costs for utility-scale projects. Major automakers are expanding long-term supply agreements for SiC components, while wafer manufacturers ramp up 200mm SiC production capacity to meet demand. For industrial applications, the shift to wide-bandgap (WBG) semiconductors is driving upgrades in motor drives, UPS systems, and industrial power supplies, creating new opportunities for analog and power chip suppliers.
