High Frequency Applications

MK Magnetics is a reliable source of high-performance magnetic core products used in numerous demanding industries for their respective applications. It includes high-frequency applications, with both standard and custom solutions for tape wound cores that provide efficiency and reliability.

High-Frequency Applications of Tape Wound Cores

As experts in magnetic core solutions, MK Magnetics understands its importance in high-frequency applications. These specialized cores are available in various configurations and materials to guarantee superior performance. However, the right design and material will depend on the nature of the application and its specific requirements.

For instance, a toroidal core can be employed in transformers due to its near-ideal design. It ensures no flux leakage since it can efficiently contain the magnetic flux inside the transformer. Meanwhile, a nanocrystalline core is ideal in machines or devices that need low core losses, even in high-frequency situations.

More high-frequency applications of our magnetic core solutions include:

Pulsed Power

In pulsed power applications, capacitors store the energy which then flows through the magnetic cores to the pulsed power device. For instance, nanocrystalline tape wound cores are a great option due to their irrefutable benefits. Since it has low core losses in high-energy situations, it’s a practical option during pulsed power research.

Some examples include:

  • Medical imaging devices (scanners)
  • High energy weapons systems
  • Lasers and lithography
  • Fusion energy research

Alternating Current

Alternating current applications, such as power conversion, suffer from eddy current losses due to the alternating magnetic field. Eddy currents generate heat, which results in energy losses, affecting the ability of the magnetic field to efficiently convert energy.

Uses of alternating current include:

  • Electric vehicles
  • Inverters used in renewable energy
  • Directional drilling

In magnetic assemblies, magnetic cores are mainly used to minimize eddy current losses. Between nanocrystalline core vs ferrite core, nanocrystalline offers better impedance at high frequencies and a more comprehensive operational temperature range. In this case, nanocrystalline is a more robust material when choosing a magnetic core.Nanocrystalline also has a much higher saturation flux density of approximately 1.23 Tesla.

Directed Energy Weapons Systems

Directed energy weapons encompass weapons that destroy their targets using highly focused energy. It doesn’t have a solid projectile, so that it can travel at the speed of light. As a result, there’s a higher demand for magnetic core products that can accommodate the frequency that high‐energy accelerators require. These are also a low cost alternative to traditional projectiles and explosives.

Some examples of directed energy weapons include:

  • Microwaves
  • Lasers
  • Particle beams

Food Decontamination Systems

As technology advances, more industries will require sophisticated solutions for high-frequency applications. An example is the food and beverage processing industry, which commonly uses high-energy systems to eliminate bacteria and other pathogens, preventing contamination to increase food safety.

Common types of food decontamination systems include:

  • Infrared heating
  • Radiofrequency
  • Microwave systems
