| 摘 要： | 本文提出一种对不规则形状印制电路板(PCB)导体进行简化计算的方法,以某变频空调室外机主板上的正、负直流母线PCB导体为例进行了简化,通过解析公式计算得到它们的电感,并与简化前用电磁场数值计算软件求得的电感进行比较,证明这种简化方法是有效的.通过在PCB导体的等效电路模型的输入端施加电压激励,比较输出端的仿真计算和实验测量结果来验证模型中参数,结果表明简化后PCB导体的电感参数是准确的.这种PCB导体的简化计算方法简便易行,具有较大的实用价值.

| Abstract: | In order to calculate the inductance of printed circuit board(PCB) conductor of irregular shape by analytic expression,it is necessary to simplify them to ones of regular shape.In this paper,a simplification method is proposed and applied to the power bus conductors in the main board used in the outdoor unit of a variable frequency air conditioner.The analytic solutions of the inductances obtained after simplification are compared with the ones calculated by electromagnetic field numerical calculation softw... |
