| 摘 要： | 采用电流注入法对某型直流固态继电器输入端与输出端的电磁脉冲损伤机制及失效模式进行了实验研究，结果表明：输入端注入电磁脉冲信号时，输出端会产生误动作，并可造成输入电路中三极管BE节产生短路损伤，导致输入端施加控制信号时输出端无法导通；输出端注入电磁脉冲信号时，可造成输出电路中MOSFET管的栅极和漏极产生短路损伤，导致输出端短路。

| Abstract: | The electromagnetic pulse(EMP) damage mechanism and failure modes are obtained for the input port and output port of solid state relays by current injection method. The results show that the output port would misoperate when the EMP signal is injected at input port, and the input port may lose its control function when the base-emitter junction of the transistor in input circuit is burned out by the signal, that is, the output port would not be switched into conduction when control sygnals are applied to the input. The output port can be shorted when the drain and source are damaged by injected EMP signals at output port. |
