高频平板型功率变压器

High-Frequeny Planar Power Transformers

近年来很多新的电源设计采用了平板型功率变压器。平板变压器和普通铜线变压器制成的电源相比，降低了高度，提高了功率密度，并具有良好的耐久可靠性。本文阐述了平板型功率变压器的结构和优良特性，并介绍了简易设计方法。

Planar Power Transfoemers can be found in many new power supply designs today. These Planar- transformer-based power supplies feature a fraction of the height of supplies based on conventional copper wire-wound transformers, with high-power densities and good long term reliability. In this articlec construction and excellen characteristics of planar power transformers were presented, a fast and easy method to make designs for planar power transformers were introduced.
