'Magnetics Design 5 - Inductor and Flyback Transformer …
Section 5 Design limitations: The most important limitingfactors in Inductor Design are (a) temperature rise andefficiency considerations arising from core losses andac and dc winding losses, and (b) core filter inductors (buck-derived) --singleand multiple windings are seldom operated in thediscontinuous current mode because of the addedburden this places on the output filter capacitor, andbecause it results in poor cross-regulation in multipleoutput supplies. Typically operated in the continuousmode with peak-peak ripple current much smallerthan full load current, ac winding loss is usually notsignificant compared to dc inductors , boost inductors and flybacktransfonners are all members of the "power Inductor "family. They all function by taking energy from theelectrical circuit, storing it in a magnetic field, andsubsequently returning this energy (minus losses) tothe circuit.
ous mode, with significant core loss, total loss is at a broad minimum when core and winding losses are approximately equal. But when inductors are de-signed for the continuo~s mode, core loss is often negligible, so that the t~talloss limit can be allocated entirely to the windings. General Considerations --Core
