Hyperscale Power

What Hyperscale Power does

Hyperscale Power AG is a Swiss deep-tech startup founded in 2025 in Zürich by Dr. Daniel Rothmund (CEO) and Dr. Sami Pettersson (CTO), both ETH Zürich alumni with over a decade of experience in solid-state transformer (SST) and medium-voltage power electronics research. The company develops rack-scale solid-state transformers that replace conventional 50/60Hz iron-core transformers, using wide-bandgap semiconductors (Silicon Carbide and Gallium Nitride) to achieve 98.5% energy conversion efficiency, approximately 10x size reduction, and ~90% less material usage versus legacy solutions. Its SST platform converts medium-voltage AC grid power (13.8kV input) directly to 800V DC output required by next-generation AI infrastructure, supporting up to 3.30MW system power in a single rack-mountable unit with full real-time control over power flow.

The company's product addresses a critical infrastructure bottleneck: AI server racks are projected to require up to 10x more power within two years while occupying the same physical footprint, while conventional transformer-rectifier systems face 18-24 month supply delays and consume 15-20% of data center facility space. Beyond AI data centers and hyperscalers (the primary target), the platform is positioned for EV fast-charging infrastructure, solar PV and wind renewable energy projects, and industrial/maritime/railway applications. The technology natively supports direct integration of battery storage and renewable energy sources without facility redesign.

Hyperscale Power operates a direct enterprise field sales model, targeting AI data center operators, EV charging infrastructure providers, and large-scale renewable energy developers through technical discussions and documentation sharing. The company is pre-commercial with products in prototype development; R&D is based in Switzerland with production expected to scale in another European location. In March 2026, Hyperscale Power closed a €5 million seed round co-led by climate-tech investor World Fund and deep-tech investor Vsquared Ventures, with capital allocated to prototype development, lab and office establishment, and hiring of senior power electronics and mechanical engineering talent. The company has been selected for Ignite Next's Spring 2026 deep tech accelerator cohort and maintains an ecosystem partnership with Infineon for wide-bandgap semiconductor supply.

Core offering

Hyperscale Power develops and manufactures solid-state transformers (SSTs) that replace conventional 50/60Hz iron-core transformers at the medium-voltage entry point of energy-intensive facilities. Their rack-scale SST systems use wide-bandgap semiconductors (Silicon Carbide and Gallium Nitride) to convert 13.8kV medium-voltage AC grid input directly to 800V DC output for AI data centers, EV fast-charging infrastructure, and renewable energy projects, achieving 98.5% conversion efficiency in a form factor approximately 10x smaller than existing solutions.

Product overview

Hyperscale Power offers a single unified core product: its proprietary Solid-State Transformer (SST) platform. The SST is a rack-scale power conversion system designed to replace traditional 50/60Hz iron-core transformers in data centers, EV charging stations, and renewable power projects. The company targets environments where power density, space efficiency, and conversion efficiency are critical constraints, offering systems with 98.5% efficiency, 13.80KV input voltage handling, 800V DC direct output, and up to 3.30MW system power capacity in a form factor 10× smaller than conventional solutions.
