Breakthroughs in Magnetic Core Materials Upgrade Performance Limits of Next-Generation Toroidal Power Inductor June 1, 2026, Munich, Germany At the 2026 European Power Electronics Exhibition, multiple material research institutions and magnetic component manufacturers jointly released the latest progress of new soft magnetic materials, which comprehensively optimize the core performance of the next generation toroidal power inductor , realizing simultaneous breakthroughs in miniaturization, low loss and high saturation current. Traditional mainstream toroidal power inductor mostly adopts manganese-zinc ferrite cores, which have good high-frequency characteristics but low saturation magnetic flux density, restricting the upper limit of carrying current. The newly industrialized nanocrystalline and amorphous alloy toroidal core materials greatly improve the performance ceiling of the toroidal power inductor : compared with ferrite core products of the same volume, the new mat...
