It is important to getting ideal high voltage pulse on matching impedance that designing exactly the inductors of stacked Blumlein pulse forming networks. Inductance design principle was aquired from several aspects: consistency of charging voltage, distortion of output wave, efficiency of stacked voltage and amplitude of load pre-pulse, a inductor was fabricated with manganese-zinc ferrite magnetic core and tested. Results show saturated plus remain magnetic induction intensity is 1.7S, saturated and non-saturated magnetic permeability are about 3.3,1462, respectively, saturated and non-saturated inductance are 7.3 mH,3.2 mH,respectively.%为了利用级联Blumlein型脉冲形成网络在高阻抗负载产生理想的高压平顶脉冲输出,开展了构成该脉冲功率源关键单元的始端电感和终端电感设计.从充电电压一致性,输出脉冲不发生严重畸变,高的电压叠加效率,可接受的负载预脉冲幅值出发,确定了始端电感和终端电感值的计算方法,利用锰锌铁氧体磁芯的饱和特性设计电感,通过实验开展锰锌铁氧体磁芯参数测试.研究表明锰锌铁氧体饱和和剩余磁感应强度之和约为1.75,饱和磁导率约3.3,非饱和磁导率约1 462,饱和电感值为7.3 mH,非饱和电感值3.2 mH.
