Section 4 – Power Transformer Design

Energy Storage in a Transformer Ideally, a transformer stores no energy–all energy is transferred instantaneously from input to output. In practice, all transformers do store some undesired energy: • Leakage inductance represents energy stored in the non-magnetic regions between windings, caused by imperfect flux coupling. In the
