Conducted Electromagnetic Interference Quantification and Suppression Method Based on Fuze Interface Compact Model
In order to solve the problem of always using experimental verification methods for electromagnetic compatibility design in the process of fuze design,which is difficult to design suppression circuits through quan-titative calculation of conducted interference at the fuze interface,a conducted electromagnetic interference quan-tification and suppression method based on the compact model of the fuze interface was proposed to quantitative-ly analyze the conducted electromagnetic interference of the fuse and design interference suppression circuits.Based on the compact model theory,this method used the equivalent circuit model of inductance and capacitance to establish a compact model of the interface device.A vector network analyzer was used to measure the actual impedance frequency curve of the device,and ADS software was used to calculate the model parameter values based on the compact model of the device,achieving the modeling of conducted electromagnetic interference in the interface device.A suppression circuit based on the calculated model transfer function expression was de-signed.The experimental results showed that the interface conducted electromagnetic interference model and suppression method could truly reflect the high-frequency signal transmission characteristics of the device,and calculate and suppress the amount of conducted interference of different external injection interference signals through the interface device,and the suppression circuit could achieve interference noise suppression effect.
