2. Evaluate peak ac flux density At this point, one should check whether the saturation flux density is exceeded. If the core operates with a flux dc bias Bdc, then B + Bdc should be less than the saturation flux density Bsat. If the core will saturate, then there are two choices: • Specify B using the Kg method of Chapter 14, or

If a material is permeable, then a greater flux density will occur for a given magnetic field intensity. The relation between B (flux density) and H (the effort to establish the field) is m= permeability (Wb/A-t m). H = Magnetic field intensity (Wb/A-t m). This relation between B and H is valid up to saturation, when further increase in H has ...

Saturation flux density in ferrite is much less than with the tape-wound or powdered metal cores: ==O.3T (3000Gauss) vs. ==O.8T. This might seem to be a dis-advantage, but saturation is not a real limitation at IOOkHz or above. In a transformer application, the maximum flux swing is restricted by losses to much less than BSAT.
