Abstract
Abstract Disclosure is made of a low-inductance (L = 0.5 to 3 mH) controlled discharger for commutating megampere currents, having a maximum controllability range with respect to voltage, and a small operation lag. The low inductance and high transmitting capacity are due to the formation by a creeping discharge of a multichannel (from 10 to 40 channels) breakdown over the surface of a thin-layer dielectric element. Two main electrodes and one control electrode placed therebetween are arranged on one side of a dielectric element of a flat or cylindrical shape, whose reverse side has a current-conducting layer. The multichannel discharge accounts for small electrode erosion and, in combination with the gas-generating properties of the dielectric, ensures multiple operation of the discharger.

Claim 1
Independent Claim
149 words
A controlled discharger comprising direct and reverse current buses; two main electrodes electrically coupled to a load and a power source with the aid of said direct and reverse current buses; a control electrode arranged between said main electrodes; an initiating pulse channel having one of its poles electrically connected to said control electrode; a dielectric element having said main electrodes and said control electrode mounted on one of its sides, its opposite side being provided, at the portion corresponding to the gap between the main electrodes, with a current-conducting layer electrically connected to at least one of said main electrodes and the other pole of said initiating pulse channel, the thickness of said dielectric element being less than the distance between said main electrodes, so that as an initiating pulse is applied to said control electrode, a multichannel discharge is formed on the surface of said dielectric element.
