摘　　要：针对传统变压器的局限,提出采用柔韧性好的同轴电缆和高导磁率的铁基非晶磁性材料绕制的1∶4阻抗变换的传输线变压器(TLTs)作为输出变换装置,并进行相关的实验研究。根据传输线理论及波的折反射分析了实际工程中的最佳匹配条件以及实际情况中阻抗失配引起的波形畸变;给出了磁芯材料对脉冲的响应分析。实验结果表明:TLTs对输出脉冲的响应良好,改善了波形前沿,减小了能量损耗,且与理论值具有较好的一致性。The 1 ： 4 transmission line transformers （TLTs） made of the good flexible coaxial cable and the high-permeabili- ty iron-based amorphous magnetic material were put forward, and applied to the output transform devices. Related high voltage pulse experimental research was carried out. The optimum impedance matching and the wave aberration because of the impedance mismatching in actual project were deduced and obtained based on the transmission line theory and the principle of the reflection and refraction of traveling waves. Also, the response of the magnetic core material to the pulse was analyzed. The results show that the TLTs have good response to the output pulse, including the improvement of rising time, and the decrease of energy con- sumption, and that the test result is consistent with the theoretical calculation result.
