Driven by power converters and third-generation semiconductor materials represented by Gallium Nitride and Silicon Carbide, the magnetic components industry is moving towards higher frequencies and integration.
Previously, different magnetic core materials had distinct application segments in different frequency ranges. For example, ferrite was suitable for high-frequency ranges of several hundred kHz, powder cores for mid-frequency ranges, and amorphous nanocrystals for low-frequency ranges. But now, the characteristics of these core materials are starting to overlap, particularly as magnetic powder core materials are rapidly developing towards higher frequencies, which complicates material selection.
The application of magnetic core materials in the fields of new energy and AI power supplies is increasing, and their nonlinearity characteristics are evident, in contrast to the linear characteristics of ferrite.
Currently, the cooling methods for magnetic cores or magnetic components mainly include water cooling plates and ventilation. These methods continuously increase power density. The design of magnetic core materials must now consider saturation, then loss, and subsequently temperature rise and thermal design, which is a clear trend.
In the past, magnetic component manufacturers often designed magnetic components based on the frequency requirements of power supply manufacturers. Now, conversely, power supply manufacturers often impose design requirements on magnetic component manufacturers based on limited volume space and loss, giving magnetic component manufacturers the opportunity to design appropriate operating frequencies and thereby potentially lead the determination of frequencies. Power supply manufacturers are then willing to cooperate with the frequency chosen by magnetic component manufacturers.
In summary, the widespread application of power converters has made the trend towards higher frequencies and integration of magnetic components inevitable. However, as the key material for magnetic components, core materials have complex characteristics, significant measurement errors, difficult modeling, and lack intuitive selection methods, becoming bottleneck issues in practical analysis and design.
