What Traftor does
Traftor is a Chinese-European privately held manufacturer of toroidal inductors and transformers for power electronics applications, founded in 2008 and headquartered in Shenzhen with manufacturing operations in Luoyang (Henan Province, China) and engineering offices in Thônes (France, near the Grenoble electrical-electromagnetism cluster) and Geneva (Switzerland). The company's core technology is proprietary toroidal core winding technology — originated in Poland over 30 years ago and industrialized by Polish and Chinese teams — that uses fewer coil layers and eliminates the yoke found in conventional E/EI/C cores, achieving up to 98% efficiency, 2-3x smaller and lighter components, and up to 20% cost reduction versus conventional solutions. The product portfolio spans toroidal inductors (500VA to 500kVA), low-voltage transformers (500VA to 2,500kVA), medium-voltage transformers (30kVA to 20,000kVA), flat-wire inductors for high-frequency applications (10-100 kHz), PCB planar transformers, classic EI/C core products, and, as of March 2026, mass-market-ready Solid-State Transformers (SST) validated to IEC 60076-3 and IEC 60270.
Traftor generates revenue primarily through custom-engineered hardware sales with project-based pricing via an online RFQ platform, supplemented by free technical consultation and co-design services. The go-to-market is enterprise direct sales with regional contacts covering APAC, EMEA, and the Americas, anchored by enterprise customers including Schneider Electric, Emerson, and Eaton (which named Traftor a Best Supplier 2023 among its 30,000+ supplier base). Vertical focus is data center infrastructure (UPS, MV/LV distribution, HVAC drives), power grid, renewable energy, automotive, and telecommunications. The company markets through industry conferences (PCIM, APEC), technical content, and direct enterprise engagement.
Supporting the product engineering is proprietary design software combining AI-driven optimization with finite element analysis and multi-physics simulation. Traftor holds certifications to EN61558, UL, IEC 60076-3, and IEC 60270, and complies with EU conflict minerals regulation. The company received a 1 million yuan Chinese government grant in 2015 following its China Innovation and Entrepreneurship Competition award, and is privately held with no disclosed institutional venture capital or private equity funding.
