From ships to servers: why AI is reshaping data center power
This blog post by Michael Geissmann explaines how AI is reshaping data center power architectures, highlighting the shift towards DC systems and the critical role of solid-state technologies in ensuring efficiency, reliability, and scalable protection.
Solid-state DC circuit breakers in traction systems
Electrified rail systems are evolving fast, but are their protection systems keeping up? In this whitepaper, Anju upadhyay examines how high-frequency switching power electronics (IGBTs, SiC MOSFETs), bidirectional energy flow from regenerative braking, and increasingly complex DC architectures expose the limitations of mechanical and hybrid circuit breakers. The paper explains why ultra-fast, solid-state DC circuit breakers are becoming critical for fault selectivity, system reliability, and safe operation in both rolling stock and traction infrastructure.
Our Successes
The AC railway neutral section switch
Continuous power supply to the locomotives while passing the neutral section by appyling solid-state technology. Just as the traditional mechanical solution, the Astrol solid-state railway switch is installed at both ends of the neutral section and allows its electrification from either side.
DC Grid Protection of Cadeler’s A-Class Wind Turbine Installation Vessels (WTIVs)
The DC multi-bus ring system, engineered by Kongsberg Maritime and protected by Astrol’s 1.5 kV, 3 kA solid-state DC breakers. These advanced breakers offer ultra-fast, arc-free fault isolation, ensuring optimal safety, uptime, and resilience in demanding marine environments.
