SEMIKRON and Silicon Mobility BEV Inverter Collaboration

The inverter platform delivers from 10 kW to 50 kW and combines the SEMIKRON SKAI® 3 LV inverter and Silicon Mobility OLEA® inverter and electric motor control solution.

SEMIKRON provides the power and assembly with an advanced integrated MOSFET module with connected DC-link, gate-driver, protection functions, and sensors. It comes with a complete 3-phase motor-drive and a ready-made power section to offer an ultra-compact MOSFET inverter. The converter connects easily to a custom control board for quick and easy designing, while leaving the control to the customer. The OLEA T222 Starter Kit includes a reference control board integrating T222 FPCU, a powerful control chip, and APP INVERTER, a control software application adapted for the SKAI 3 LV inverter power module, fully configurable to support a wide variety of 3-phase PMSM and WRSM electric motor and position sensors. The application provides efficient and safe torque and speed management using Field Oriented Control (FoC) and variable Space Vector Pulse Width Modulation (SVPWM) algorithms from 2 kHz up to 100 kHz. Calibration and validation are enabled thanks to its native ASAM standard support. The starter kit also includes vehicle dependent software demo code, post-build measurement, configuration, calibration, and firmware update GUI software. The platform is accessible as a White Box where users can customize upon request the power module packaging/casing from SEMIKRON and access the OLEA APP INVERTER object code through a dedicated license. “With this platform, we give low-voltage vehicle manufacturers access to technologies and solutions far above today’s state of the art implementations, providing them the extra edge for their designs,” commented Karl-Heinz Gaubatz, CEO/CTO SEMIKRON International. “By choosing this platform, vehicle manufacturers can accelerate the electrification of their vehicles and offer themselves the possibility of future differentiation,” added Rainer Kallenbach, CEO Silicon Mobility.
