提出一种经济实用的闭合磁芯式脉冲变压器,对原有脉冲变压器加以改进,以提高耦合系数减小漏感,减少输出脉冲电压上升沿时间。采用电磁感应原理分析并进行试验测试,通过对原有的脉冲变压器增加反向并联辅助绕组接入初、次级绕组加以改进,对脉冲变压器的耦合和输出特性进行研究,对重要参数进行测量和计算。试验中的脉冲信号为占空比5%、频率10kHz的方波脉冲,采用有辅助绕组的脉冲变压器,比无辅助绕组的脉冲变压器的输出脉冲电压上升沿减少了200ns,试验结果证实该理论设计具有合理性。

A kind of pulse transformers with auxiliary windings applied to PEF

Puts forward a kind of economical and practical pulse transformer with closed magnetic core type, to improve the original pulse transformer, in order to improve the coupling coefficient and decrease the leakage inductance, thus reducing the rising time of output pulse voltage. Using electromagnetic induction principle to analyze and test, to improve the original pulse transformer in adding a reverse parallel auxiliary winding to connect the primary and secondary windings, to study the coupling and the output characteristics of pulse transformer, to take measurement and calculation of the important parameters. The pulse signal of the test is square wave pulse of the duty ratio 5%, the frequency 10 kHz, the rising time of the pulse transformer output pulse voltage of with the auxiliary winding than the with no auxiliary winding less 200 ns, the experimental results verify the rationality of design.
