Power Electronics for Vehicles

Electrical vehicles require highly reliable power electronics. SEMIKRON, a leading supplier of power electronics, has been 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 as well as industrial and material handling vehicles.

Applications

SEMIKRON offers products for every possible application in the automotive environment. The dedicated automotive portfolio includes power modules and systems. Our power modules are found in light duty vehicles such as passenger cars and lightweight trucks up to 7 tons. Our 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.
