Nuremberg, Germany, and Sophia Antipolis, France (April 15, 2021) - SEMIKRON, a leading manufacturer of power electronics, and Silicon Mobility, a solution provider of digital control for electrified powertrain, today announced the availability of a 24V to 96V inverter platform for automotive battery powered vehicles and industrial off-road vehicles. The Inverter platform delivers from 10KW to 50KW and combines the SEMIKRON SKAI® 3 LV inverter and Silicon Mobility OLEA® inverter and electric motor control solution.

An Ultra-Compact MOSFET Inverter system

SEMIKRON, on one hand, provides SKAI® 3 LV, 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 performance power solution for 3-phase motor-drive and a ready-made power section which reduces time to market. All of this is proposed within a custom-made cover to offer an ultra-compact MOSFET inverter. The 3rd generation of the SKAI LV industrial MOSFET inverters constitutes the 7th generation of inverter technology manufactured by SEMIKRON, with more than 1.5 Million MOSFET inverters in the field. The 3rd generation is a platform concept that offers standard design versions or can be customized to meet user’s needs. The converter connects easily to a custom control board for quick and easy designing, while leaving the control to the customer. 

A highly configurable and intuitive control solution

Silicon Mobility, on the other hand, delivers OLEA® COMPOSER – T222 Starter Kit for SKAI3 LV, the digital control and software aspects of the platform. It includes a reference control board integrating OLEA® T222 FPCU, a powerful control chip, and OLEA® 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 2kHz up to 100kHz. It also includes numerous configurable safety mechanisms for faults detection and reaction such as overcurrent, overvoltage, and overtemperature. 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.

A jump-start for fast system development and open for customization

The combined solution offers users access to an optimized, best-in-class, and full sketch Power + Control Inverter Platform. A ready-to-go service is available at both SEMIKRON and Silicon Mobility to help customers immediately get their hands on the solution enabling fast prototyping and development of any industrial or automotive system. 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 Silicon Mobility, a technology leader in ultra-fast control schemes, a perfect match is formed for high quality, high-performance solutions for low-voltage vehicle applications,” declared Karl-Heinz Gaubatz, CEO of SEMIKRON. “With this platform, we give low-voltage vehicle manufacturers access to technologies and solutions far above todays state of the art implementations, providing them the extra edge for their designs.”
