摘要
主要设计了直流电源在强电磁脉冲环境下的保护电路,阐述了设计思路,并进行仿真和实验验证。防护电路设计采用瞬态元件和滤波电路互相配合使用。瞬态元件主要是电压箝位和电流的泄放,滤波电路是滤波和延时作用。仿真与实验结果表明,防护电路可以对强电磁脉冲进行衰减,可以有效保护直流电源。
A DC power protection circuit in electromagnetic pulse environment is designed in this paper. The design thinking is expounded. And simulation and experiments are completed.The protection circuit is composed of a transient element and a low-pass filter. The main functions of the transient element are voltage clamping and current discharge, and those of the low-pass filter are filtering and time delay. The results of simulation and experiments show that the protection circuit can attenuate the electromagnetic pulse, which can protect the DC power supply effectively.
