Automotive

Development partner & series supplier for safety-critical control units and power electronics

High-performance solutions for Automotive

Silver Atena is the driving force behind the electrification of mobility: We develop competitive products – from pre-development and prototypes to SOP and series production. Our focus is on electric motor inverters and DC/DC systems, as well as safety ECUs up to ASIL-D.

These form the basis for high-performance drive technologies, chassis and torque vectoring applications, highly efficient on-board power supply and charging solutions, and intelligent vehicle safety architectures.

Automotive Focus Areas

  • Inverters (High Voltage, High Speed, Powertrain & Electric Motor) 

    Development of high-voltage inverters – including high-speed applications. From system and controller development to series production.
