High-Voltage Traction Inverter
What is a High-Voltage Traction Inverter?
Our inverters for controlling electric motors form the central control unit of the electric powertrain. They impress with their exceptional energy efficiency, compact design, and maximum reliability – even under extreme conditions in axle drives. Developed for use in 400 V and 800 V electrical systems, our traction inverters are ideally suited for modern electric vehicles and hybrid applications – including commercial vehicles.
Whether as an add-on or integrated solution, the inverters can be flexibly integrated into various vehicle architectures and offer maximum performance in a minimal installation space. Thanks to state-of-the-art silicon (Si) and silicon carbide (SiC) semiconductor technology, our systems achieve particularly high efficiencies across virtually the entire operating range – crucial for long driving ranges.
For a dynamic driving experience, our inverters deliver high currents for strong torque – even at low speeds. Furthermore, our systems support the synchronization of two electric motors on one axle – ideal for targeted torque distribution to improve driving dynamics and stability.

Advantages
High efficiency across all operating points ensures optimal energy utilization, which directly translates into a longer range and reduced cooling requirements. At the same time, the high power density enables a compact design while maintaining consistently high performance – a crucial advantage for smaller and lighter drive systems.
High switching frequencies enable precise motor control, which has a positive impact on driving characteristics, for example, in functions like torque vectoring. This is complemented by high-performance control technology that significantly improves dynamic response and driving stability.
Finally, the multilevel architecture contributes to efficiency optimization and opens up possibilities for greater range or the use of smaller batteries.
