Nanocrystalline No Ferrite in 2020
Nanocrystalline No Ferrite in 2020 In switching power supplies, nanocrystalline common mode chokes have better characteristics than ferrite core common-mode chokes, the surge current and spike voltage they generate will form interference sources. If not suppressed, these interferences will cause damage to the load equipment or the switching power supply itself. In EMI filter circuits, the differential mode is often used inductance and common mode inductance is used for corresponding suppression. The differential mode inductance is mainly responsible for filtering out the differential mode interference signal between the two wires of the input or output end, and the common-mode inductance is mainly responsible for filtering out the common-mode interference signal of the two incoming wires. The commonly used common-mode filters are mainly ferrite core materials. However, the weakness of ferrite is also obvious, such as poor temperature characteristics, low saturation magnetic ...
