Electrical vehicles require highly reliable power electronics. Semikron, a leading supplier of power electronics, has bee supplying products to the EV markets for more than 10 years.

From chips and modules to entire converters, the full range of Semikron products can be found in passenger cars, utility vehicles, trucks, buses and industrial and material handling vehicles.

Semikron offers products for every possible application in the automotive environment. The dedicated automotive portfolio includes power modules and systems.


Power Electronics for Electric Vehicles

Semikron’s power modules are found in light duty vehicles such as passenger cars and lightweight trucks up to 7 tons. Semikron’s SEMiX baseplate modules are used by leading Chinese manufacturers of electric vehicles. For higher power density, SKiM63/93 is the first choice for electric as well as plug-in electric vehicles. The SKAI 3 LV, a MOSFET based inverter stack, is perfect for mild hybrid vehicles based on 48VDC bus systems.

For heavy duty vehicles, Semikron offers not only the SEMiX and SKiM63/93 power modules, but also a full inverter system the SKAI 2 HV for up to 850VDC bus. Heavy duty vehicles refer to heavy duty trucks and buses in electric or hybrid configurations.

Battery vehicles, such as forklifts, agricultural and construction vehicles, race cars and motorcycles are powered by SEMiX and SKiM63/93 power modules as well as by the low-voltage MOSFET system SKAI 3 LV.

Semikron’s Key Facts

  • 150,000 SKiM 63/93 drive electric and hybrid buses, passenger cars and electric motorbikes
  • 10,000 buses use SKiM 5 in pre-assembled stacks: power module + driver + heat sink
  • More than 200,000 hybrid and all-electric cars are powered by SEMiX power modules
  • 53,000 SKAI 2 HV drive electric and hybrid buses
  • 1.5 million SKAI LV drive vehicles for material handling
