Abstract :
Magneto-cumulative generators are high-power sources of magnetic energy pulses. Duration and shape of the pulses, created by these generators lies in a rather narrow range, which is determined by detonation velocity of the most powerful high explosive substances, used in these generators. Different schemes and device for generator parameters agreement with load parameters are used for formation of current pulses of different shape and duration on a wide load values range. These schemes and devices include inductive coupling of generator contour with load contour, accumulation of magnetic energy, created by MCG and its commutation to the load using breaking units, which use phase transition metal-insulator at conductor temperature increase, current open switches and different types of plasma-erosion open switches. The main purpose of these schemes and devices is to create current pulse of required shape with comparable or higher power value, than developed by MCG, on the load. We describe the source of high-power energy pulses, based on MCG. Transformer energy bending from MCG, breaking units, made of electrically exploding wires, and noncontrollable sharpening discharger are used in this source.
