Fundamentals of Power Electronics Chapter 15: Transformer design13 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:
