Measurements and Performance Factor Comparisons of Magnetic Materials at High Frequency
The design of power magnetic components for operation at high frequency (HF, 3–30MHz) has been hindered by a lack of performance data and by the limited design theory in that frequency range.

| Summary: | The design of power magnetic components for operation at high frequency (HF, 3–30MHz) has been hindered by a lack of performance data and by the limited design theory in that frequency range. To address these deficiencies, we have measured and present core loss data for a variety of commercially available magnetic materials in the HF range. In addition, we extend the theory of performance factor for appropriate use in HF design. Since magnetic materials suitable for HF applications tend to have low permeability, we also consider the impact of low permeability on design. We conclude that, with appropriate material selection and design, increased frequencies can continue to yield improved power density well into the HF regime. |
