摘要: 在理论分析分数比脉冲变压器输出脉冲上升时间与变压器次级绕组匝数、磁芯截面积和伏秒积等参数关系的基础上，设计建造了一台初次级等效比为1∶43.4分数比脉冲变压器，等效到次级的漏感为157.3 μH，分布电容为412.4 pF。低电压实验得到负载上的脉冲上升时间为894 ns，高电压实验得到负载上的脉冲上升时间为917 ns，电压幅值42.7 kV，表明所设计建造的分数比脉冲变压器达到了设计要求。Abstract: The fractionalturn ratio pulse transformer was theoretically analyzed, including the relationship between rise time and the number of secondary winding turns, area of magnetic core cross section as well as voltagetime product. A 1:43.4 turn ratio pulse transformer was designed and built accordingly. The secondary leakage inductance is 157.3 μH and the stray capacitance is 412 pF. The rise time is 894 ns in low voltage test. High voltage test of the pulse transformer connected with a 420 Ω fictitious load has been performed in oil. An output pulse with a peak voltage of 42.7 kV and a rise time of 917 ns was generated．
