摘要:
A power electronics module includes a capacitor having a trough-shaped housing and at least one capacitor winding. An electronic unit includes a base on which the capacitor is mounted. A cooling plate in thermal contact with a cooling surface of the capacitor is formed by a bus bar. The cooling plate is on the base of the electronic unit.

The present invention relates to a power capacitor (1) for the installation in a motor vehicle, comprising a capacitor unit (2) with at least one first and at least one second capacitor element (3, 4) whereby each capacitor element comprises at least two rolled-up plastic films that are provided with metal layers and are provided with metal-free edge strips on mutually opposite lying longitudinal sides, a circuit connection unit (5) and a housing (12), whereby the capacitor elements (3, 4) are circuit-connected in parallel by means of the circuit connection unit (5).
摘要:
A housing can be used for high-power components, especially high-power capacitors. A housing has a carrier platform made from a suitable electrically insulating material and a preferably metallic cover, wherein the thermal expansion coefficients of the platform and of the cover are matched to each other. This matching is achieved according to the invention by adjusting the glass-fiber coefficient of a fiber-composite material.
摘要:
The invention relates to a metallization for a film capacitor, wherein a dielectric capacitor film provided with a metallic coating is wound into a capacitor element in the running direction of the capacitor film, whereby the coating is provided with a segmentation.
摘要:
An electric roll-type capacitor with contacts at the ends thereof, includes a dielectric formed of plastic foils wound together with a mutual offset, and an electrode in the form of regenerable thin metal layers disposed on part of at least one of the plastic foils defining an edge of the at least one plastic foil free of the metal layers, the metal free edge of the at least one plastic foil having a cut formed therein, and the offset being at most 0.2 mm wide, and a method for manufacturing the same.
