PCB平面变压器漏感与自互感精确仿真

从变压器完备的自互感模型出发导出漏感表示式，表明精确的自互感模型是漏感精确估值的前提。通过电磁仿真软件CST电磁工作室叼寸一个四绕组多层PCB平面变压器模型的自互感进行仿真计算，说明上述结论。

Leakage Inductance Calculation by Accurate Simulation of Self-Mutual Inductance in Planar Transforme

In this paper, leakage inductance expression of windings is deduced from self-contained self and inductance matrix. To approach the errorless estimation of leakage inductance, the premise of accurate self and inductance matrix is proved. A four windings multilayer PCB planar transformer model is simulated in CST EMS leakage inductance of windings is calculated to give evidence of the previous conclusion.
