摘　　要：针对诸如变压器绕组形变的脉冲测试法等宽带测试需求,设计了一台由计算机控制并显示脉冲信号源工作参数、基于场效应管的可调纳秒脉冲信号源。实验测试表明,在50Ω负载上脉冲源能产生高斯上升沿20ns、指数下降沿40～200ns分档可调、重复频率0～5kHz连续可调、幅值0～1kV连续可调、体积为32×30×7cm3的纳秒脉冲电源,可满足变压器绕组形变的宽带测试需求。A nanosecond pulse generator based on MOSFET is designed,its running parameter could be adjusted and displayed by computer,aiming at broadband test requirements such as the pulse transformer winding deformation test method,and it owns miniaturization profile of 32×30×7 cm3.The experimental results show that the pulser can generate electrical pulse with Gaussian rising time of 20 nanoseconds,section-adjustable index falling time of 40—200 nanoseconds,continuously adjustable repitition frequency of 0—5 kHz,quasi-continuously adjustable amplitude of 0—1 kV at 50 Ω load.And the pulser could meet the requirement of transformer winding deformation testing.
