摘要

文中以扫频阻抗法为理论基础

提出了适用于扫频阻抗法仿真分析的双绕组变压器分频段等效电路模型。首先以扫频阻抗曲线第1个峰值点对应频率作为分频点

将整个频率区间划分为低频段与高频段

其次从耦合电感出发推导出了适用于低频段的集中参数的变压器"T"型等效电路

对应高频段建立分布参数的梯形等效电路

最后

在10 Hz

MHz的扫频范围内

通过试验与仿真的对比验证了该模型的准确性。

Abstract

In this paper

on the basis of sweep frequency impedance method（SFI）

the equivalent circuits of double-winding transformer

which are suitable for SFI simulation analysis

are proposed with the difference of the frequency range. Firstly

the entire frequency range is separated into low frequency range and high frequency range by the frequency which is corresponding to the first peak impedance value in SFI curve. Secondly

a transformer lumped parameter T-equivalent circuit in low frequency range is established by analyzing the coupled inductors. In high frequency range

a distributed parameter ladder equivalent circuit is used for SFI analysis. Finally

the accuracy of the equivalent circuits is validated by means of a comparison between measured and emulated SFI results in a wide frequency range from 10 Hz up to 1 MHz.
