From the first schematic to a production-ready board, for space, defense, and industrial systems.
A full-stack approach to power and analog electronics, from the first sketch on a notepad to a fully characterized, production-ready board. With proprietary tooling built in-house.
End-to-end product development. We turn an idea into a fully functional, production-ready board, schematic, layout, BOM, characterization.
Auditable, traceable documentation that supports every line of your design, from prototype to qualification. We comply with applicable standards without overclaiming.
Numerical modeling that aligns your design with the state of the art, efficiency, footprint, thermal behavior, EMC, all under control before tape-out.
Hands-on guidance from senior power-electronics engineers. Custom programmes, intensive workshops or long-term mentoring, we sit with your team, unblock projects and transfer practical know-how.
We develop and maintain in-house Python tooling that gives us a structural edge on rigorous design problems, running locally on our machines, no cloud dependency.
A typical project at ADEV, eight steps, all handled in-house from the technical scoping to the lab characterization of the final board.

The kind of hardware we deliver, from regulated multi-kilovolt high-voltage supplies to ultra-dense point-of-load converters. Client names and identifying details are withheld; everything below is described under NDA.
SPACE-GRADE
UNDER NDA
A high-voltage converter stepping a 28V unregulated bus up to a tightly regulated 10kV rail at 50W. Built for the space environment with ECSS-driven margins and a stable analog regulation loop.
SPACE-GRADE
UNDER NDA
A pair of very-low-voltage, high-current point-of-load buck converters stepping a 5-12V bus down to sub-volt (0.8V) and 5V rails, reaching 20A and 20W in an ultra-compact footprint. An aggressive power density held with fully analog control and a space-grade layout.
SPACE-GRADE
UNDER NDA
Design of a dual-output power supply converting an unregulated 28V bus into +2kV / 20W and +5V / 30W outputs. Resonant converter topology with fully analog discrete control, developed in compliance with ECSS standards for high-reliability space applications.
More case studies available under NDA request a portfolio review.
Every design that leaves the workshop has been characterized on real bench equipment. No simulation alone, actual measurements, traced and reported.
Conducted and radiated emissions screening. Lab is not formally accredited, formal qualification stays with the certifying lab.
Static and dynamic measurements on power converters, analog blocks and discrete switching devices. From DC accuracy to ns-level transient capture.
Thermal cycling and steady-state environmental stress, aligned with industrial, automotive and space mission profiles.
In-house assembly and rework on advanced packages, BGA, QFN, fine-pitch SMD, for fast turn-around between iterations.
Need equipment we don't own? We can source and rent almost any type of measurement or test equipment quickly through our network of technical partners, without delay to your project.
ADEV is led by two founders, backed by a senior network of independent experts in power electronics, analog design and mechanical engineering.
Co-Founder · PhD, Electrical Engineering
Thomas holds an M.S. in Electrical Engineering from INSA Lyon and earned his PhD in Power Electronics in June 2025 at the SATIE laboratory of ENS Paris-Saclay in industrial partnership with a leading European space-grade module manufacturer. His work focused on high-current, low-voltage output converters using GaN transistors for space applications, combining analog design with modern simulation tooling. After his thesis, he developed a commercial space-grade product and co-founded ADEV with Raphaël, pairing a research-driven approach with two decades of field-tested industrial expertise.
Co-Founder · Power Electronics Engineer
Raphaël is a seasoned power electronics expert with extensive experience in automotive and space applications. He holds an M.S. in Electrical Engineering from Polytech Paris-UPMC, Sorbonne University. His career spans Continental and Ausy, then 12 years at Valeo as electronic engineer and technical coordinator, followed by four years as Power Analog Electronic Design Expert in the space industry, leading the development of qualified DC-DC converters, an industrial track record that anchors ADEV's deliverables in real-world manufacturability.
