Abstract: A power supply module for facilitating an increased flow of cooling air comprises a chassis in which circuitry of the power supply module is housed, and a front panel associated with the chassis. The power supply module is configured with one or more airflow openings which facilitate a flow of cooling air into or out of a chassis interior and which are ensured of remaining unblocked, wherein one of the chassis and the front panel is formed with one or more inclined surfaces to define at least a part of a corresponding passageway through which air crossing a portion of the front panel is flowable. The one or more inclined surfaces is apertured to define the one or more airflow openings or an aperture in fluid communication with the one or more airflow openings.

Abstract: A current sensor includes a shunt and at least one resistant element. The shunt conveys an electric current, and has a resistance which varies with the shunt's temperature. A resistant element, which has a resistance that varies with its own temperature, is electrically connected between the shunt and an output terminal of the current sensor. At least a portion of the resistant element is in thermal contact with a predetermined location on the shunt, so that the resistant element's resistance varies in accordance with the shunt temperature. The current sensor may be connected to an amplifier whose gain varies in accordance with the resistance of the resistant element. The variation in the resistance of the resistant element causes a change in the amplifier gain, which compensates for changes in the shunt resistance due to change's in the shunt's temperature. In some embodiments, a second resistant element is connected between the shunt and a second output terminal.

Abstract: An electrical coil includes first and second electrically-conductive elements each of a thin, flat, annular configuration formed with a gap to define the turns of a 2-turn coil, and an electrically insulative element also of a thin, flat, annular configuration disposed coaxially between the two electrically-conductive elements and formed with a gap aligned with one end of each turn to permit the ends to be electrically connected together. Also described is a transformer having a secondary winding including a plurality of such 2-turn coils, and a primary winding of a plurality of double-coils each connected together at their mid-portions.

Abstract: A high-current electrical coil includes a plurality of flat, electrically-conductive strips bent to define together a coil in which the electrically-conductive strips are disposed coaxially and extend longitudinally with respect to the longitudinal axis of the coil. Each of the electrically-conductive strips is bent to define at least a part of a turn of the coil. One electrically-conductive strip has an outer end carrying a first connector terminal for the coil and projecting outwardly of the coil; and another electrically-conductive strip has an outer end carrying a second connector terminal for the coil and projecting outwardly of the coil. Each of the electrically-conductive strips includes inner ends in electrical continuity with each other, and intermediate portions electrically-insulated from each other such that the plurality of electrically-conductive strips together define a coil exceeding one turn between the first and second connector terminals.
