摘要： The invention relates to a capacitor housing for electric circuits. The capacitor housing has a closed collar, into which busbars extend, to guarantee a clean assembly and subsequent filling with resin. The collar has pairs of through openings on the upper side and the lower side for the passage of a sleeve part through each, an upper and lower sleeve part each contacting as a terminal device one of the busbars and clamping same between the end faces of the sleeve parts. The invention also relates to a link capacitor with a housing of this kind.

摘要： The invention relates to a charging device for charging a battery of a motor vehicle having an electric drive motor. The charging device has an inductor and a drive converter, which converts a direct voltage of the battery for the electric drive motor during drive operation of the motor vehicle and which has a DC link center point. The inductor, together with the drive converter, is used as a step-up converter for charging operation of the battery. The aim of the invention is to provide a compact and economical charging device This aim is achieved in that the charging device has a controllable switching device, which is designed to charge and/or discharge the DC link center point to a voltage.
