电源的雷电浪涌效应及加固技术研究

雷电浪涌是雷电对电子系统的一种重要的作用形式。雷电对电子系统的影响主要表现在对电源电路的浪涌破坏和干扰上。为研究雷电浪涌对电源的冲击效应,进行了雷电浪涌对直流电源的冲击实验。实验表明,雷电浪涌对直流电源有很大的干扰作用,可使电源产生大的波动或高频噪声。在雷电流涌冲击实验的基础上,对直流电源进行了加固实验,并取得了良好的效果。

Study on Effects of Thunder Surge on Power Supply and Hardening of Power Supply

Thunder surge is an important form that the thunder acts on electronic systems.The effects of the lightning on electronic systems are the surge destruction and interference to power supply.In order to study the striking effects of thunder surge on power supply,the striking experiments on power supply were carried out.The experiments show that thunder surge has a strong interference effect on the power supply,and can generate a distinct fluctuation or high-frequency noise.Based on the experiments,the hardening experiments for the DC power supply were made,and a good result was obtained.
