Where Are Nanocrystalline Cores Used in Modern Transformers?
As power electronics continue to move toward higher frequency and higher power density, magnetic components are playing an increasingly important role in transformer design.
Nanocrystalline cores are finding growing applications in medium-frequency and high-frequency transformers, particularly where low core loss, high magnetic flux density, compact size, and thermal performance are important.
Typical applications include:
Medium-Frequency Transformers (MFT)
MFTs are widely considered for next-generation power conversion and electrical energy systems. Operating at frequencies well above 50/60 Hz, they require magnetic materials with suitable high-frequency performance and power density.
DAB & Bidirectional DC/DC Transformers
Dual Active Bridge (DAB) converters are increasingly used in energy storage and bidirectional power conversion. Their high-frequency isolation transformers can benefit from nanocrystalline cores designed for high power density and efficient energy transfer.
Energy Storage & PCS
In energy storage systems, high-frequency isolation transformers and DC/DC converters are important components of power conversion systems. Nanocrystalline cores can be considered when designers are looking to optimize efficiency, size, and thermal performance.
Solid-State Transformers
Solid-state transformers rely on power electronics and medium-frequency transformers to achieve voltage conversion and electrical isolation. Nanocrystalline materials are attracting attention as a potential core material for these high-frequency magnetic components.
High-Frequency Power Supplies
Nanocrystalline cores are also used in selected high-frequency power supplies, industrial power equipment, EV charging systems, and other power-electronic applications.
