Transient Response and Transfer Characteristics of EMC/EMP Protection Circuits Containing Nonlinear Filter Pin Connectors

Protection circuits (with non-linear components) against LEMP- and NEMP-induced interfering currents are of special interest. In case of NEMP interfering signals steepnesses with values up to lo kV/ns may occur. Concerning the overvoltage protection of electronic aircraft systems the protection circuits have to show low weight and small dimensions. These characteristics are of special significance because in case of multiconductor transmission lines a lot of protection circuits have to be installed. Special protection and filter circuits with regard to non-linear filter pin connectors (FPC), have been developed and tested by LEMP and NEMP interfering signals.
