Magchoke – Applications

The Magchoke technology is especially suitable where inductors must handle, at the same time, a fundamental frequency of e.g. 50 to 300 Hz while simultaneously and effectively filtering higher frequencies generated by e.g. switch mode power supplies and/or harmonics leaving the fundamental frequency undistorted. The Magchoke is suitable for both air and liquid-cooled solutions.

Examples of suitable products MagComp specializes in are:

  • LC filters
  • LCL filters
  • Sinus filters

Typical applications we specialize in are inductors and filters for:

  • Uninterruptible Power Supply systems (UPS)
  • Solar Inverters
  • Active Harmonic Filters
  • Wind Power Generation
  • Regenerative Drives
  • Low Harmonic Drives
