Abstract: PROBLEM TO BE SOLVED: To provide a film for a film capacitor or the other capacitive components. SOLUTION: When a capacitor is charged in operation, such a strong electric field that may cause an electrical breakdown can be generated at the end of a conductor 2. Basically, in this invention, an end region film layer is formed at the end of a conductive layer forming an electrode, and the film layer is partly charged during the time intervals determined by the change of an applied voltage, for example, in AC current intervals, the film layer has a feature that it is only partly charged. Therefore, the end region film layer must have a smaller surface conductivity than the surface conductivity of the conductive layer. That the end region film layer is only partly charged means that there is almost no discontinuity in voltage distribution, which enables to avoid a large uprise in field strength.

Abstract: PROBLEM TO BE SOLVED: To provide a capacitor for high voltage that has self-curing property without releasing very high energy even during breakdown, and that can operate without any loss even when AC current is used. SOLUTION: This capacitor is wound by at least one sheet of foil (1) provided with a supporting foil (3) used as a dielectric and at least one sheet of conductor layer (4). It is provided with an internal series circuit. The conductor layer (4) covered on the dielectric or the conductor layer is divided in a plurality of areas (4.1 and 4.2), comprising the internal series circuit. The areas (4.1 and 4.2) are correlatively arranged, or they are connected with each other in some case so that a number of unit capacitors connected in series may be formed. The capacitor is superior because a current passage structural body is formed on the areas. COPYRIGHT: (C)2003,JPO

Abstract: A film (1) comprises a base (2) consisting of an electrically insulating polymer which carries on one or both surfaces a sequence of electrically conductively coated areas (3) which are separated by non-coated interstices (4). The film or a superposition of films arranged one above the other can be shaped, i.e., folded or preferably wound to form a capacitor with a plurality of essentially parallel electrodes which are insulated from each other and consist each of one or more electrode layers formed by the coated areas (3) and separated by dielectric layers formed by sections of the base (2). An electrode layer may comprise two adjacent coated areas pertaining to subsequent turns. The capacitor has high voltage withstand capacity and can be used, e.g., as a high voltage capacitor in a capacitive voltage transformer in series with a conventional low voltage transformer wound from two superposed conductively coated films.

Abstract: The invention relates to an arrangement consisting of series-connected ultracapacitor or supercapacitor cells (1, 1'). Thyristor diodes (6) are connected to the cells in parallel and serve as overvoltage limitors. The arrangement can provide power even with defective cells. Only a limited voltage is released in the thyristor diode short-circuiting a defective cell. Beyond a particular power density, the diode forms a short-circuit path, hereby ensuring that the arrangement continues to function reliably. A bipolar arrangement of the capacitor electrodes (12) is preferable, enabling the internal resistance of the arrangement to be reduced further. Direct integration of the thyristor diodes allows a compact construction.

Abstract: The capacitor has a dielectric carrier film (1) applied with a conductor layer (4), which is divided into sectors (4.1, 4.2). The sectors that are mutually arranged to form two elementary capacitors, defines a current path structure such that the conductor layer has a high sheet resistance than the current paths (5, 6) of the current path structure.

Abstract: The invention relates to a foil for a foil capacitor, comprising an electrically insulating carrier foil with an electroconductive layer placed thereon. The electroconductive layer in the foil capacitor forms an electrode and the carrier foil forms a dielectric. The invention is characterized in that the electroconductive layer (2) is as thin as possible and that at least one current path (4, 5) is provided in order to reduce the overall surface resistance on the electroconductive layer (2). Said current path has a lower surface resistance than the electroconductive layer.

Abstract: The invention relates to a method for producing glass-like carbon, according to which a film or plate made of polycarbonate is cross-linked by a pre-treatment and is subsequently pyrolyzed in an inert atmosphere or in a vacuum. The pre-treatment can be, for example, a tempering of the film in an oxidizing or reducing atmosphere at a temperature ranging from 200 DEG C to 600 DEG C or can be an irradiation of the body or can be induced by additives in the polycarbonate resin.

Abstract: 16 Film capacitors have a thin carrier film (1) as dielectric. The surfaces of the carrier films are provided with conductor layers (2) - serving as electrodes - made of metal or made of a nonmetallic conductor. It the capacitor is charged during operation, electric fields with large field strengths can arise at the edges of the conductor layers (2), which can lead to breakdowns. The invention is essentially distinguished by the fact that an edge zone coating (3) is present at the edges of the electrode- forming conductor layer (2), which edge zone coating is only partly charged in the time periods - for example of the alternating-current period - which are critical for changes in the applied voltage. To that end, the edge zone coating of the film must have a surface conductivity which is less than the surface conductivity of the conductor layer. The only partial charging of the edge zone coating has the result that the potential profile has scarcely any discontinuities and large field strength increases can thus be avoided.
