Toroidal Cores for Switched Mode Power Supply
|
Characteristics:
A toroidal core of nanocrystalline alloy applied in switched mode power supply has the advantages of high permeability and low loss, and is thus an ideal material for the main transformer of uni-polar, push-pull or bi-polar type of high frequency switched mode power supply, magnetic amplifier, choke cores, energy storage inductor, filter inductor, resonant inductor, common mode inductor and sharp peak choke.
