SiC semiconductor components are capable of handling the extreme operating conditions of automotive applications and can still offer additional benefits such as lower system costs and higher power density.
The use of SiC components in master drive inverters and on-board chargers (OBC) will rapidly increase in the next few years and the prices of SiC components will reach a sweet spot at 2.5 times higher than those of Si components by 2023.
With the SiC components, automakers will be able to reduce system costs while enjoying falling SiC component prices year after year.
