Data Information

FAQ

Q: What are Siemens' primary business areas and fields of operation?

A: Siemens is a leading technology company focused on four core business areas: industry (digital industry and automation), infrastructure (intelligent infrastructure and smart buildings), mobility (rail transport solutions), and healthcare (through Siemens Healthineers, a separately publicly listed company majority-owned by Siemens) .

Q: What are Siemens' proprietary technologies in power electronics and grid protection?

A: Siemens has developed advanced power electronics including an optimized clocked buck-boost converter with dual switch elements and a regulating unit that generates separate control signals for buck and boost modes, enabling efficient input-to-output voltage conversion. For grid protection, Siemens has pioneered an optimized protection system using grid-protection units (GPUs) that detect fault signals and disconnect power lines or generation units, combined with inverter-based resource supervisory controllers (IBR SC) that are co-optimized through a protection system co-optimizer to maximize dependability, security, and operation speed during grid faults. The company also offers dynamic isolators that monitor voltage differences across busbars and automatically connect or disconnect electrical groups based on real-time conditions.
