Silicon carbide semiconductors make electric cars more efficient
• Harald Kroeger: “Silicon carbide semiconductors bring more power to electric motors. For motorists, this means a 6 percent increase in range.”
• Only Bosch is equally at home in the automotive and the semiconductor industries.
• With its new semiconductor plant in Dresden, Bosch is strengthening its competitiveness.
Nowadays, all cars feature semiconductors. There are more than 50 of them in every vehicle that rolls off the production line. The new microchips made of silicon carbide that Bosch has developed will now help electromobility make a great leap forward. In the future, the chips made of this extraordinary material will set the pace in the power electronics – the command center for electric and hybrid vehicles. Compared to the silicon chips used to date, SiC semiconductors have better electrical conductivity. This enables higher switching frequencies while also ensuring that much less energy is dissipated in the form of heat.
