Abstract

Abstract

A pulsed magnetic field simulation system was developed to study the effect of microelectronic system under strong magnetic pulses. In the experiment, personal computers were put into the electromagnetic environment of the simulator. Coupling paths, interference threshold, the relation of the threshold with rising time and duration time of the field were studied by changing the peak value, duration time and rising time of the simulated pulsed magnetic field. Results show that the connecting cables are the main paths that introduce interference, simple shielding can reduce the interference at some extent, and the interference is more potential to affect the microelectronic system if its time derivative is larger．
