PULSE VOLTAGE GENERATOR Russian patent published in 2021 - IPC H03K3/00 H03K3/53 

FIELD: high-voltage pulsed technology.

SUBSTANCE: invention relates to high-voltage pulsed technology and can be used in direct-action accelerators designed to register fast processes (for example, for pulse radiography) in polygon conditions. The generator contains several stages with capacitors and a spark gap in each stage, charging columns of inductance coils located along the generator axis between the walls of the housing and the elements of the stages, an insulating medium - compressed gas in a sealed metal housing, the stages are fixed on a dielectric stand, a spark gap of at least the first stage executed manageable, the capacitors of the stages are equipped with protective metal screens with rounded edges, the stand is made in the form of a central plate on which the stages are staggered, the capacitors are combined in series-parallel assemblies and installed on additional plates located on the sides of the stand perpendicular to it and the generator axis, the plates are attached to the stand with dielectric screws and reinforced from the sides with flat dielectric elements, capacitors are fixed on the plates in pairs and symmetrically with respect to their planes, the inner leads of the pairs of capacitors are connected by metal pins, the outer leads of the capacitor assemblies are connected in parallel with metal connecting buses, the spark gaps are fixed with dielectric screws on the stand perpendicular to it and are electrically connected to the capacitor assemblies using cylindrical pins entering the collet contacts on the connecting buses of the assemblies of adjacent stages, the stage capacitors are charged through two potential and two grounded columns of inductance coils.

EFFECT: expansion of operational capabilities by increasing the capacity of the discharge circuit, ensuring effective shielding of high-potential nodes and PVG elements, eliminating the consequences of possible arcing of high-current contact connections, ensuring ease of access to any node or element.
