Low Br and Linear Magnetization Characteristics Nanocrystalline Cores
Product Detail:
For IGBT inverter electric welder and pulsating DC fault current voltage independent RCCBS which low Br is needed to get high¡÷B(Bs-Br),the nanocrystalline cores are made with transverse-field-annealing processes.
(1).Comparision of nanocrystalline cores with other soft magnetic cores.
