变压器 – 平面

技术规格

平面型磁性组件的出现为传统磁性组件的设计增加灵活性和优势。虽然可以看出几何差异（主要是成品的总高度），但平面型几何结构提供了数个设计优势。平面磁芯通常具有较大的中心磁芯腿横截面积，这减少了实现所需磁化电感需求的导线匝数。平面磁性装置成品使用印刷电路板 (PCB) 绕组、交错螺旋绕组或环冲压扁线或键片式绕组进行组装。这些形式中的每一款都可以在装置中产生线匝，几乎不需要绕线筒或线圈架来绕线。

planar magnetic devices

由于扁平线或分层 PCB 迹线绕组和交错绕组，这两项组件物理布局方面造就更高的电流能力、良好的散热和低寄生漏电。由于较大的中心腿磁芯几何形状和磁芯材料的选择，可实现低磁芯损耗。具有高效磁芯自屏蔽和绕组紧密耦合的平面磁设计，其紧凑特性也具有 EMI 优势。

所有这些设计优势使得具有良好导热和散热性能的低高度组件具备更高的体积功率密度、更低的损耗和更高的效率。
