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.
Power Modules for Electric Drive Systems (EDS)
eMPack® Power Module – High Performance Package for E-mobility
The transition from full vehicle platforms to full battery electric vehicle architectures is progressing rapidly. These architectures will require scalable power electronics solutions for electric drive systems (EDS) that are capable of covering a wide power range and are cost-effective at the same time, resulting in an important competitive advantage for vehicle manufacturers.
SEMIKRON’s new power module platform eMPack, which is based on a common module concept, is being developed for EDS inverter architectures covering a power range from 100kW up to 750kW.
eMPack covers 400V and 800V battery system applications. The combination of silicon carbide technology with SEMIKRON’s fully sintered, low stray inductance Direct Pressed Die Technology (DPD) enables unmatched power densities combined with high reliability for automotive application.
