When switching power supply using a large capacitor filter, the input power factor is between 0.5~0.7. However, domestic and international standards ask that the input power factor of switching power supply has to achieve more than 0.9, which means the power factor correction circuit must be used to improve the power factor. Compared with 0.1mm thick silicon steel cores, the Fe-based amorphous alloy core for PFC inductor in 20kHz 2.5kVA power factor correction circuit, making the iron loss from 28.8 W down to 4.4W and the weight reduces from 4.75kg to 4.2kg. Nanocrystalline's flexible production size and lower lost make it the ideal material for PFC inductor, especially for high - frequency switching power supply.
