Flyback transformer design considerations for efficiency ...
www.ti.comThe flyback transformer is responsible for a large percentage of the total losses in a flyback power stage. There are four categories of losses: • Core losses. • Copper (winding) losses. • Transition losses. • External losses. Core losses occur in the transformer’s ferrite core and depend on the core’s flux density (amplitude,

www.ti.comous 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

arxiv.orgA transformer requires a sequence of embeddings2(e.g., word embeddings) as input. To adapt this ... As the core component of transformers, the self-attention module incurs the O(N2) computational/memory cost, where N is the length of an embedding sequence.
