EMI filters are widely used in power electronics converters to meet EMI standards, and the common‑mode inductor—often the largest magnetic component—must be optimized for size and cost. The study investigates and compares datasheet and experimental data of magnetic materials for common‑mode choke design. The authors evaluate common‑mode choke materials—including amorphous iron, nanocrystalline, ferrite, and iron‑nickel alloys—using finite‑element analysis and experimental tests, comparing effects such as dimensional resonance, eddy currents, and core geometry. Finite‑element analysis of ferrite and nanocrystalline materials is validated by experimental measurements.
EMI filters are widely used in power electronics converters to meet EMI standards. Since the common-mode inductor is often the largest single magnetic component, it must be optimized for size and cost. This paper investigates and presents datasheet and experimental comparisons of the magnetic materials aimed for a common-mode choke design. Several magnetic materials are considered: amorphous iron, nanocrystalline, ferrite and iron-nickel alloys. The material analysis compares and contrasts various effects, such as dimensional resonance, eddy current and core geometry. Finite element analysis is validated with experimental investigation of selected magnetic materials: ferrite and nanocrystalline.
