What BrightLoop Converters does
BrightLoop Converters (legal name Bright-Loop SAS) is a French power electronics designer and manufacturer founded in 2010 and headquartered in Paris, with industrial operations in Lannion and a precision machining subsidiary, BrightLoop Mechanics, in Dourdan. The company was acquired by ABB and now operates as a development partner within ABB's Traction division. BrightLoop designs and produces DC/DC converters, DC/AC inverters, and motor drive inverters built on a proprietary nested (cellular) power conversion topology in which small, replicable converter cells are parallelized to manage power ranging from kilowatts to project-proven deployments of 10 MW. The architecture integrates wide-bandgap semiconductors — silicon carbide (SiC) MOSFETs for high-voltage systems and gallium nitride (GaN) HEMTs for low-voltage systems — together with high-frequency galvanic isolation transformers operating up to 300 kHz, which the company states deliver AC-DC conversion systems 5,000 times smaller than conventional grid-frequency transformers. Power densities reach up to 35 kW/kg and 60 kW/L, with conversion efficiencies up to 99% and N+1 redundancy for fault tolerance.
The product portfolio spans LV-LV buck-boost converters, HV-LV isolated DC/DC converters, HV-HV and ultra-high-voltage (up to 2,400 VDC) DC/DC converters, bidirectional three-phase AC/DC inverters, high-speed motor drive inverters for aerospace, and dedicated DC galvanic isolators, supported by a Simulink-based digital twin simulation platform and a partner portal. BrightLoop sells primarily through direct enterprise engagement to international OEMs and Tier 1 manufacturers across seven end-markets: motorsport and hypercars (Formula E, Extreme E, F1), off-highway (construction, agriculture, mining), transportation (rail, bus, truck), aerospace and defense (eVTOL, defense — backed by the French DGA), maritime, hydrogen fuel cells, and AC microgrids/infrastructure. Named customers include GreenGT, Glydways, Beyond Aero, AeroDelft, and Flying Whales, with strategic technology partnerships with EPC (GaN), Navitas, and ABB.
Revenue is generated through hardware sales of standard and custom-configured power converters plus precision machining services from BrightLoop Mechanics, with annual production capacity of up to 5,000 converters at the Lannion facility. EMS partnerships support higher-volume scaling. Pricing is not publicly disclosed; all sales are negotiated through direct enterprise engagement. The company holds ISO 9001, MIL-STD-461G, ECE R10/R100, LV123/LV124, IP67/IP6K9K, and EN62368-1 certifications, with DO-160/178/254 aeronautics standards in progress. No revenue figure is publicly disclosed.
