Protections Against HPM Front-Door Coupling: A Survey of Commerical Limiters

摘要

This report provides a survey of commercial limiters. There is a number of different technologies that potentially can by used for circuit protection against HPM front-door coupling and other electromagnetical interferences. One of the aims with this report is to serve as the basis for deciding on which protection devices shall be purchased and tested regarding their potentials for protection against HPM. The other aim is to create a general survey of different technologies/types of limiters that can be used for HPM protection. Essential properties of the different limiter technologies have been investigated in order to sort out which ones can be of interest. The conclusion is that only a few limiters meet the demands for protection against HPM front-door coupling. These limiters are probably best used in a combination to achieve a good overall protection. Front-door protections can be used in the future network centric defense, where the systems for communications and sensors, has to be protected from harmful pulses.
