Electric turbocharger
What is a High-Speed Inverter?
Our highly integrated high-speed inverters are specifically designed for operating turbo compressors in modern fuel cell and combustion engine vehicles. They control extremely compact high-speed compressors that efficiently and reliably deliver the required airflow at six-figure speeds.
Thanks to their powerful hardware architecture and precise control algorithms, the inverters ensure optimal interaction between the compressor and the fuel cell system or engine – even in minimal installation space. The perfect solution for maximum efficiency, dynamics, and reliability in mobile applications.
Features
- Modern inverter architecture: from classic B6 bridges to sophisticated multilevel converters for maximum efficiency.
- Wide voltage range: use of silicon or silicon carbide semiconductors (Si/SiC) for systems up to 800 V.
- Motor-optimized control: precisely tuned inverter to motor type, application, and operating conditions.
- Flexible system design: diverse control concepts for different application requirements – from the compressor to the drive unit.
- Comprehensive sensor technology and monitoring: monitoring of speed, sensorless rotor position detection, current, voltage, and temperature.
- Advanced safety functions: integrated protection through HV interlock, active discharge, short-circuit and overvoltage protection, and temperature monitoring.
- Development according to safety standards: requirements-based according to functional safety (ASIL level) and industry standards.
Applications
- Intake air compression in fuel cells
- Electric turbochargers for combustion engines
