Nanocrystalline Filtercores for high efficient power electronic systems
Filter cores made of nanocrystalline material are particularly characterized by the adjustability of very high permeabilities (about 20,000 – 200,000μ) with the smallest component size, a saturation flux density Bs = 1.2T and vanishing saturation magnetostriction (<5ppm) as well as an extremely good temperature resistance, up to 130°C remains almost constant. Especially in times of new technologies by rapidly switching IGBTs (eg Silicon Carbide ,SiC‘ or Gallium Nitride ,GaN‘) the exigence on the EMC filters is getting higher and higher and makes the use of nanocrystalline toroidal cores for the filter technology more and more essential. By its special properties, not only space and weight can be saved but also an extremely good HF/RF attenuation can be achieved.
