Description: The analysis of scientific literature is in-process resulted about the powerful SVCH pulsers which utillize energy of relativism electrons. Comparative descriptions of generators are given with the different types of electrodynamic stru ctures. The analysis of power-levels is resulted depending on a wave-length for the different types of generators. The level of development of this direction is rotined in Ukraine. Resulted separate examples of the use of such devices with a mil itary purpose in foreign countries.
Keywords: relativism electrons, electrodynamic structures, magnetron, vircator, generators of overbroadband impulses
