摘要： A power electronics module (100) for enhancing short circuit failure mode (SCFM) transitions. The module is adapted to disconnect a gate unit (102) from the module using a first switch (104), upon a failure of at least one of a plurality of semiconductor chips (201) during which the failed chip enters an SCFM, and connect a passive circuit arrangement (103), including at 5 least one capacitor (106) and at least one resistor (107), to the module using a second switch (105). The passive circuit arrangement is adapted to switch on at least one of the remaining non- failed semiconductor chips.

摘要： The invention relates to a direct methanol fuel cell and to a method for controlling the methanol concentration without requiring the provision of additional methanol concentration sensors (47). Instead, the current-voltage characteristic curves of the fuel cell (40) are sampled using small variations of the system variables current I and methanol concentration M, and information used for controlling is obtained therefrom. In systems possessing an electrical buffer (49), a connected consumer is supplied without interruption despite the abandonment, as described by the invention, of the optimal operating point of the fuel cell.

摘要： Said lead-through has a current conductor (1) to which high voltage can be fed. A section of the current conductor (1) is surrounded by a varistor array (9). The lead-through also contains two supply terminals (4, 6), one (6) of which can be connected to high voltage and the other (4) is connected to ground, a lead-through insulator (5) provided between the current conductor (1) and the varistor array, in addition to a clamping device (11) that exerts a contact force on the supply terminals (4, 6) and the varistor array (9) placed in the form of a sandwich between the latter. The clamping device has an insulating part that exerts a contact force on both supply terminals. The lead-through insulator is embodied in the form of a shaped body and has a support element provided with a guide surface for a contact (1a) of a plug-type connector that is connected to a current conductor (1) with a cable or a lead-through of an electrical device.

摘要： The aim of the present invention is to optimize a capacitative level detector, which is particularly suitable for determining the location of a boundary layer (12) between water (10) and oil (11) in a separator tank. The known sensor principle consists of measuring the environment-dependent capacity between neighbouring electrodes (13, 4; 4, 5; 5, 6) of a rod-shaped probe (1). The invention is characterized in that the probe (1) is designed in such a way that in a more conductive medium (10) large ionic double-layer capacities occur at the electrodes (4, 5, 6, 13) and in a more isolating medium (11) small capacities are present between the electrodes (4, 5, 6, 13). To this end, the invention provides for a large electrode size (h), a relation of electrode size (h) to electrode distance (a) preferably in the range 1

摘要： 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.
