Abstract: A waveguide absorber which withstands high mechanical and thermal loads is typified in that a member (4) exhibiting absorber material is clamped between waveguide walls (5, 6) in such a way that at least one wall region (5) adjoining the member (4) is constructed flexibly, and that a force acting on the flexible wall region (5) presses the latter against the member (4).

Abstract: A transformer arrangement for generating rectified, high voltages has a primary winding wound around the transformer core and is surrounded by a metallic shield. A mass of insulation material, including an insulation layer, surrounds the metallic shield. A secondary winding is embedded in the mass of insulation material outside the insulation layer. The secondary winding has an end terminal carrying a high alternating voltage potential and presents an outer circumference. A heat conducting metal band rests on and covers a major portion of the outer circumference of the secondary winding but does not constitute a short-circuit winding for the transformer. The terminal end of the secondary winding is connected electrically and thermally with a plurality of rectifiers via the metal band.

Abstract: An arrangement for mounting circuit components which operate at high power densities at high potential levels, which arrangement includes means defining a major and a minor insulating layer on the latter of which the components are mounted, the arrangement including a metal shield embedded between major and minor insulating layer and formed to partly surround the components, and a connection for applying to the metal shield a potential selected to minimize the potential between the components and the shield, wherein the shield and the minor layer are formed for enabling the shield to receive power dissipated by the components at high heat flux density and for heat received by the shield to be removed through the major layer with low heat flux density.

Abstract: In a high power density transformer composed of a core and a coil assembly unit (or two such units), with the coil assembly unit including a primary winding, a secondary winding, a coil carrier supporting the windings, an insulating system, and a metal shield between the primary and secondary windings which is in electrically and thermally conductive connection with a metal grounding structure so that the metal grounding structure constitutes a support for the coil assembly, the metal shield serves as the coil carrier which is disposed directly on the metal grounding structure.

Abstract: A direct voltage-direct voltage converter including: a transformer having at least one primary winding and at least one secondary winding; first and second electronic switches connected to the primary winding; a rectifier unit connecting the secondary winding to a load; and switch control circuitry connected to the electronic switches for closing the switches periodically and in alternation at a selected repetition rate in response to pulses produced by a clock pulse generator, for applying a direct voltage across the primary winding and periodically reversing the polarity of that direct voltage across the primary winding.
