Compared to the silicon chips used to date, SiC semiconductors have better electrical conductivity, the company stated in a release. This enables higher switching frequencies while also ensuring that much less energy is dissipated in the form of heat.

Advantages of using SiC microchips

According to Bosch, semiconductors made of silicon carbide set new standards for switching speed, heat loss, and size.

It all begins with additional carbon atoms, which are introduced into the crystalline structure of the ultra-pure silicon used to manufacture semiconductors. The chemical bond created in this way turns the semiconductor chips into real powerhouses. Especially for applications in electric and hybrid vehicles, this means many advantages.

In power electronics, they ensure that 50 percent less energy is lost in the form of heat. This saving translates into more efficient power electronics and more energy for the electric motor and therefore for the battery range. Motorists can drive 6 percent further on a single battery charge.
