Utility Electric Vehicles
The utility electric vehicles segment today comprises primarely the traditional material handling market where battery operated vehicles like fork-lifts have been well established for decades. Semikron Danfoss has been serving this market for more than 20 years and offers complete SKAI inverter systems for low voltages as well as for voltages of 800VDC.
The electrification of vehicles in the agriculture and construction sector, in contrast, is still in its infancy. There is, however, substantial potential for this area to grow in the future thanks to the cost benefits of battery driven functions. SKiM 93 power modules are the ideal choice for traction drives, while our SKAI HV inverters, which can incorporate auxiliary functions as well, are suitable for higher integration levels. The utility vehicle segment typically relies on industrial standard products.
E-Mobility
The e-mobility segment includes passenger cars as well as medium/heavy duty buses and trucks and light electric vehicles. This market is driven by statutory CO2 emissions limits and the components and systems used in e-mobility applications must comply with automotive standards. Compactness and inverter efficiency are the key to reducing energy consumption in electric vehicles. The high-volume passenger car segment is the fastest growing e-mobility market.
Semikron Danfoss adresses this market with dedicated modules for traction drives - the DCM and the eMPack. For the bus and truck market, Semikron Danfoss also offers complete SKAI inverter systems. The light electric vehicle market, a highly fragmented market with power ranges of up to around 40kW, includes two-wheelers, small delivery trucks, recreational / neighborhood vehicles and many more smaller, yet fast growing niches. SKAI LV is the dedicated product for these applications.
Product Highlights
Power Module Platform
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 changing conditions that occur during cold start and repeated acceleration and deceleration. Semikron Danfoss 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.
Our 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).
The transition of complete car platforms to full electric battery vehicle architectures is progressing rapidly. These architectures will demand scalable power electronics solutions for electric drive systems (EDS) that are capable of realizing a wide performance range in an economic way, resulting in competitive advantage to vehicle manufacturers.
Semikron Danfoss’ 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.

Power Module Platform
To power up the fast-growing fleet of HEVs, PHEVs and BEVs, Semikron Danfoss has developed a power module technology platform, DCMTM, for traction applications. With silicon (Si) and silicon carbide (SiC) being the main cost-drivers in power modules, our DCMTM technology platform aims at reducing the semiconductor surface enabled by combining patented technologies.
At the same time, the DCMTM also increases power density, reliability, robustness and lifetime of the inverter. By selecting the best fitting chips from a competitive supplier base and by carefully selecting the power module components, package and electrical configuration, we are able to use the semiconductors to their full potential.
The DCMTM technology platform is designed to be scalable. In the same package, we can scale the power up or down to meet different inverter voltage classes with blocking voltages of 750V-1200V, while having different output currents from 350 to 900A.
Furthermore, our power modules are based on quality components, patented packaging and cooling technologies to achieve outstanding, measurable results in terms of reliable performance and robustness – all adding up to ensure a cost-effective solution that lasts.
Our certified processes assure for consistent high quality and streamlined path from development to volume manufacturing.

Compact Power Electronic System
Hybrid electric or all-electric buses are already in widespread use in our cities today and are an effective way of reducing pollutant emissions or avoiding them altogether. This move towards cleaner mobility is also being seen in trucks, with more and more manufacturers introducing hybrid electric or all-electric trucks to their fleets.
In heavy-duty off-road utility vehicles such as construction site vehicles and agricultural machinery, the power electronics are exposed to particularly harsh ambient conditions. They have to be ultra-compact and lightweight, while exhibiting good vibration, impact and shock resistance in order for them to work reliably on uneven terrain. They have to be able to work at both very low and very high ambient and coolant temperatures and boast excellent thermal and power cycling capabilities at the same time.
