Chapter 15 Transformer Design
ecee.colorado.edu2. 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

www.ti.comSaturation 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.
