矩阵拓扑结构脉冲变压器

基于集中参数模型分析了脉冲变压器分布参数、变比、负载阻抗等对输出波形前沿和过冲的影响。在此基础上对传统脉冲变压器、矩阵变压器的分布参数进行了分析对比,分析结果表明相对于传统脉冲变压器,矩阵变压器可获得更小的漏感值,但分布电容将有所增大。设计建造了两台变比分别为1∶60,1∶120传统脉冲变压器及变比为1∶120的矩阵变压器,实验研究表明矩阵变压器可获得更小的上冲特征系数,其分布参数与理论分析结果相吻合。

Matrix topology pulse transformer

Based on the lumped circuit model, the influences of parasitic elements of pulse transformer, turns ratio and impedance of load on the rise time and overshoot of output waveforms are discussed. The relationship of the parasitic elements between the standard pulse transformer and matrix transformer is analyzed. Matrix transformer with smaller leakage inductance and larger parasitic capacitances is compared to the standard pulse transformer. The standard pulse transformers and matrix transformer are designed and built. The matrix transformer with smaller characteristic coefficient is compared to the standard pulse transformer. The relationship of parasitic elements between pulse transformer and matrix transformer is the same to the theoretical result.
