Amorphous and Nanocrystalline Cores

Tape-wound toroidal and oval cores made of nanocrystalline VITROPERM® or amorphous VITROVAC® offer low losses over the full permeability range between µ~700 to µ >>100,000.

Benefits:

  • F-, R- and Z-type hysteresis loops
  • Wide range of core dimensions and permeability levels
  • High saturation magnetization
  • Flat temperature characteristics
  • Epoxy coating or plastic core boxes

Toroidal Cores for Common Mode Noise Suppression

  • Frequency converters for drives
  • Cores with epoxy resin coating for operating temperatures up to 120 °C
  • Cores with plastic casing for operating temperatures up to 130 °C
  • Prominent core sizes are available at different permeability levels for optimizing insertion loss characteristics vs. DC bias capability
     

Toroidal and Oval Cores for Common Mode Noise Suppression

  • Ambient temperature: -40 °C < Ta < +105 °C
  • Max. continuous operating temperatures of Top = 130 °C or Top = 150 °C (check table below)
  • Automotive qualified according to AEC-Q200
  • Production in IATF 16949 certified VAC production facilities
  • Design taking into account ‚Technical Cleanliness‘ acc. to VDA 19 Part 2 and ZVEI guideline ‚Technical Cleanliness in Electrical Engineering‘
     
  • Developed for noise suppression of the high-voltage DC battery or
  • At the DC output of the drive inverter as well as the AC output of the drive inverter in hybrid and electric vehicles

Cores for Current Transformers in Electronic Energy Meters

  • Nanocrystalline and amorphous cores for very small amplitude errors even under DC bias
  • Low and constant power error for various load conditions
  • Various standard types in table below

Core Stack Assemblies with Nanocystalline Cores

Single-turn chokes employing a number of nanocrystalline cores assembled in a stack are an effective solution for bearing current problems or extremely high common mode noise from other causes in large-scale variable speed drives, wind generators and other applications.

In these applications resonance phenomena cause high-amplitude interference currents with peak values ranging from several 10 A to over 100 A. These generally take the form of short and thus high-frequency current peaks. For these applications, VAC offers assembled core stacks which can be easily and securely integrated into existing applications with the minimum of effort.

 

The core stacks are available in two sizes with two different through-hole diameters. They are custom-designed, allowing an individual selection of core type and the number of stacked cores (up to 7 pieces) depending on the required saturation level and the required inductance.

The table below shows the existing core stacks. Further variants upon request.
