Abstract

To meet the application requirement of kA level pulse current injection, a kind of current injection probe based on amorphous magnetic core is designed. Then the circuit model is established based on the injection probe structure, and the model parameter values, frequency domain and time domain are verified by the particle swarm optimization algorithm. Finally, the performance difference between the kA level injection probe and the traditional injection probe (FCC-120-6A) is analyzed.
