Inductive components for power electronics
For over 35 years, CEFEM has specialized in the design and manufacturing of medium-frequency magnetic components, produced at our two production sites located in France. Our expertise enables us to offer a comprehensive range of solutions, from low to high power (up to 1MW), always optimized for power density and performance.
Our magnetic components, manufactured in both small and large series, are now essential in various sectors such as railways, power quality management, renewable energy, and maritime applications. Whether molded, encapsulated, or impregnated, these components come in a variety of designs tailored to meet the specific requirements of our partners.
Total cost of ownership (TCO) is a key factor in the selection and design of your magnetic components. At CEFEM, we go beyond the purchase cost, considering all factors that impact TCO: energy efficiency, maintenance costs, lifespan, and recyclability. Our approach aims to optimize profitability throughout the entire lifecycle of your components, minimizing operational expenses (OPEX) while ensuring long-term reliability.
