High Flux Core for EV Charger

High Flux Core for EV Charger

1. Low Hc that indicates soft ferromagnetic material is easily magnetized or demagnetized by external magnetic field. That means core loss is low too.
2. High Bs and high Ms that can achieve high permeability (u) and low Hc, this can also increase magnetic flux density.

Characteristics and classification of Soft ferromagnetic materials

Characteristics of soft ferromagnetic materials

1. Low Hc that indicates soft ferromagnetic material is easily magnetized or demagnetized by external magnetic field. That means core loss is low too

2. High Bs and high Ms that can achieve high permeability (u) and low Hc, this can also increase magnetic flux density.

3. Low magnetic loss and low electric loss – this requires low Hc and high electrical resistivity

4. High Stability – High stability against changes of humidity, vibration and environment
