POWER SYSTEM TECHNOLOGY

Their core work

Power System Technology (PST) is a French SME that designs and develops power electronics hardware for aviation applications, specifically power conversion modules for aircraft electrical systems. Their core work involves building high-power-density DC-DC and DC-AC converters that manage onboard electrical power in more-electric aircraft architectures. In the ACHIEVE project they contributed to mechatronic systems for turboprop electric starter-generators; in IMPERIAL they coordinated the development of modular power conversion units for aircraft platforms. They operate in the Clean Sky 2 ecosystem, meaning their work feeds directly into European aviation industry supply chains.

What they specialise in

How they've shifted over time

PST's first H2020 project (ACHIEVE, 2017–2021) positioned them as a hardware contributor within a broader mechatronics and health-monitoring effort for turboprop electrification — no specific power electronics keywords were recorded, suggesting a supporting rather than defining role. By their second project (IMPERIAL, 2021–2023), the picture sharpens dramatically: they coordinated the effort and the technical focus is now precisely defined around DC-DC/DC-AC conversion, high power density, and decentralized distribution. The trajectory is a move from component participant to specialist lead, with power conversion becoming their explicit identity.

PST is consolidating around a tight niche — modular, high-density power converters for aircraft — and their step into the coordinator role on IMPERIAL suggests they are building enough credibility to lead future Clean Sky or Horizon Europe aviation electrification projects.

How they like to work

PST operates in small, focused consortia — four partners across three countries — which is typical for highly technical hardware development where each partner has a precise deliverable. They have demonstrated both roles: participant on a larger mechatronics project and coordinator on a focused power conversion effort, suggesting they are flexible but most valuable when the project scope matches their hardware niche. They are not a consortium hub with a broad network; they are a specialist node that joins or leads when the technical fit is exact.

PST has worked with four unique partners across three countries over two projects, a deliberately small footprint consistent with deep-specialization SMEs in aerospace hardware. Their network is narrow but likely high-quality, concentrated within the Clean Sky 2 supply chain ecosystem.

What sets them apart

PST occupies a specific and defensible position as an SME that both builds and leads development of aviation-grade power conversion hardware — a combination that is rare among small companies, most of which remain subcontractors. Their Clean Sky 2 track record gives them verified credibility with major aerospace primes, which matters when consortium builders are assembling technology-readiness-sensitive projects. For a consortium needing a focused power electronics partner with demonstrated ability to deliver aviaton-qualified hardware, PST brings both the technical depth and the project management track record to justify a non-trivial role.

Highlights from their portfolio

• IMPERIAL
  PST's largest project (€328K) and their only coordinator role — developing innovative modular power conversion units for aircraft, with a precise technical scope in DC-AC/DC-DC conversion for aviation platforms.
• ACHIEVE
  PST's entry into the Clean Sky 2 ecosystem as participant on an advanced mechatronics and electric starter-generator project, establishing their aviation electrification credentials before stepping up to lead IMPERIAL.
