摘要：

Issues related to the copper loss in the planar windings of 1-10-MHz power transformers are discussed. The relationship between current distribution, copper loss, and core geometry is investigated with the aid of finite-element analysis. Magnetizing current proximity effects are shown to cause excessive copper loss in a simple sandwich transformer, a structure formed by sandwiching the planar winding between two plates or magnetic material. Three alternative transformer structures that reduce this problem are compared.
