平面变压器任意并联PCB线圈损耗建模及设计软件开发

平面变压器并联PCB线圈的载流能力须通过建立线圈损耗模型及开发的相应软件，才能得到有效提高。基于涡流场场控方程与回路电压平衡原理，建立了任意并联长形和环形PCB线圈涡流损耗解析模型。根据线性系统叠加原理，进一步提出适用于任意连接方式的线圈损耗模型显式化处理方法及系统化编程算法，开发出具有友好人机界面的线圈损耗设计与分析软件。实验验证了损耗模型和算法是正确的。而系统化和实验相结合的方法验证开发的软件也是正确的，为设计高性能的并联PCB提供了强有力工具。

Eddy Current Loss Model and Design Tool for Arbitrary Parallel PCB Windings of Planar Transformer

Current handling capability of parallel PCB winding in planar transformer can be effectively enhanced by winding loss model and relative design tool. The analytical eddy current loss model of PCB winding with arbitrary connections for both rectangular and spiral types is built based on eddy current field equations and loop voltage balance. And furthermore, a processing method with distinct form and systematic programming algorithm are also proposed with superposition principle to code the loss model into software with friendly human-machine interface. Experiments verified the loss model and the algorithm. And the software was also ensured by systematic verification and experiments. The software provides a powerful tool for the PCB winding design with arbitrary parallel connections.
