Power Electronics for Electric and Hybrid Passenger Cars
Our Solutions for Electric and Hybrid Passenger Cars
In passenger car applications, power electronics have to rise to considerable challenges: they have to be compact and efficient, while remaining robust and reliable under the ever changing conditions that occur during cold start and repeated acceleration and deceleration. SEMIKRON offers a wide range of products that rise to the occasion in any application in the automotive sector, be it battery-powered electric vehicles, mild hybrids, plug-in hybrids or other hybrid drive vehicles. SEMIKRON’s dedicated automotive portfolio includes power modules and integrated converter/inverter systems that are often based on innovative semiconductor technologies such as silicon carbide (SiC), significantly improving efficiency in standard passenger vehicle applications in comparison to silicon-based technology (IGBTs).
In addition to high-voltage solutions with 400/800 V battery systems, mild hybrid vehicles featuring a 48 V on-board power supply are increasingly finding their way into this sector. Mild hybrids have a 48 V electric motor alongside the conventional combustion engine, providing additional power boost and energy recovery functions that reduce CO2 emissions by up to 15%. SEMIKRON modules are already in widespread use in electric vehicles. The SEMiX baseplate modules are especially popular with leading Chinese automotive manufacturers, while our well-established baseplate-less SKiM 63/93 technology is the current first choice for electric and plug-in hybrid electric vehicles for higher power densities.
