Nanocrystalline cores for magnetic amplifiers(Mag-Amp), are heat treated by longitudinal magnetic field, have high saturation flux density(Bs), high rectangle ratio(Br/Bm), low coercivity(Hc) and high curie temperature.
Mag-Amp used nanocrystalline core has virtues of high efficiency, low temperature rise, small reset current, large working current, high working temperature.
> Desktop personal computer power supply
> Server computer power supply
> Switched mode power supply
> High saturation flux density Bs=1.25T – Small size, lower turns
> High rectangle ratio Br/Bm≥94% – Low dead angle voltage, large working current
> Low coercivity Hc≤36A/M @ 100KHz, 80A/M – Low reset current, high efficiency

These cores are our standard cores, custom-made cores are availabe.
We can also custom made Co-based amorphous cores for magnetic amplifier. Co-base mag-amp core has more lower coercivity and higher efficiency, suitable for high-end computer power supplies.
