摘要： A photoconductive switch comprises a first layer (1), two contact layers (2, 3) arranged on said first layer and connectable to different potentials for applying a voltage thereacross, said first layer being adapted to be conducting upon applying a voltage across said contact layers when exposed to light from an illumination source of an energy high enough for lifting charge carriers from the valence band to the conduction band of the material of said first layer. The illumination source is an excimer lamp, in which unstable electronically excited dimers are formed when a voltage is applied across first and second electrodes (12, 13) separated by a gas or gas mixture. The dimers so formed decompose into two gas atoms while emitting a photon of an energy suitable for lifting charge carriers from the valence band to the conduction band of the material of the first layer.

摘要： An electric switching device comprises a switch means (2) which presents an electrode gap (5) which is convertible between an insulating state and a conducting state, and members adapted to cause the electrode gap to assume conductivity. These members comprise a source for generally collimated radiation, and a system for directing the radiation towards the electrode gap in order to bring the gap or at least a part thereof to the form of a plasma. The radiation directing system comprises at least one directing element (15) for applying the radiation energy along a line (13) extending between the electrodes (3, 4). The directing element (15) is designed such that, and the generally collimated radiation inciding to the directing system is directed such that the radiation energy line (13) is at least partly laterally displaced in relation to the axis (20) of the inciding, generally collimated radiation.

摘要： A device for switching electric power comprises at least one electric switching arrangement (5). This switching arrangement comprises at least one switching element (10a) comprising an electrode gap (24). This gap is convertible between an electrically substantially insulating state and an electrically conducting state. Furthermore, the switching element comprises means (25) for causing or at least initiating the electrode gap or at least a part thereof to assume electrical conductivity. The means (25) for causing or at least initiating the electrode gap to assume conductivity are adapted to supply energy to the electrode gap in the form of radiation energy to bring the gap or at least a part thereof to the form of a plasma by means of this radiation energy.
