摘　　要：介绍了直线变压器驱动源(LTD)中磁芯的工作原理,通过模拟计算分析了磁芯伏秒数对LTD输出参数的影响。通过调整磁芯伏秒数、磁芯复位状态和负载阻值等实验条件进行了一系列实验。实验结果表明:判断磁芯饱和的依据主要有输出电压显著降低、输出脉冲脉宽减小及回路过阻尼状态下出现反向脉冲等;反向电流对磁芯具有复位效应,一定条件下可将磁芯完全复位。实验结果验证了理论分析及模拟计算的结果。根据对实验结果的分析,提出了针对不同应用领域利用磁芯饱和效应进行波形调节的初步设想。Working principle of magnetic core in linear transformer driver（LTD） was introduced. The influence of the magnetic core＇s volt-second product on the output of LTD was deduced by means of simulation. A series of experiments were designed to evaluate the saturation of the magnetic core. These experiments were carried out under such conditions as different volt-second product of the core, different reset state of the core and different load resistance. Conclusions as the criteria of magnetic core saturation and reset effects of reverse current to magnetic core were drawn from the experiment results. The experiment results validate the simulation results. Application of the saturation effect of magnetic core to specific fields were suggested.
