摘要: 介绍了短脉冲应用中磁芯的选取，设计了一台两路并联馈电的单模块直线型脉冲变压器驱动源（LTD）装置。在低压情况下测试了装置对不同脉宽信号的响应特性，在此基础上利用一级脉冲形成网络提供的输出阻抗约5 Ω，脉宽约3 μs的近似方波信号对装置进行了高压实验，得到了匹配负载情况下LTD次级上的输出电压波形，和脉冲形成网络的输出波形得到了很好的吻合。建立了相应的LTD电路模型，利用Laplace变换推导了模型对有限上升前沿脉冲的响应，证明了励磁电感偏小是造成实验中LTD装置输出电压幅值明显低于充电电压的主要原因，提出了改进方法并进行了实验验证。Abstract: This paper introduces how to choose magnetic cores in the applications of narrow width pulses and the design of a onestage linear transformer driver(LTD) module powered by two parallel circuits. The LTD response characteristics of different width of low voltage pulses are measured and then high voltage experiments are carried out based on the pulse forming net with an impedance of about 5 Ω which can produce square wave pulses with duration of about 3 μs. The voltage waveforms of the secondary winding of the LTD are in good coincidence with the ouput voltage waveforms of PFN. A simplified circuit model of LTD is investigated and some important results are obtained with the method of Laplace transform. The reasons why the output voltage of LTD is lower than half of the charging voltage
