English Abstract

Planar fractional-winding transformers have the advantages of low winding losses with fractional turns and easy integration, which have shown great potential in improving efficiency and power density in recent years. The current fractional-winding transformers all adopt a completely symmetrical structure, which is too strict for the transformer structure and makes it difficult to use the space fle...
