Abstract: An electrolytic capacitor module for installation in a housing of a motor vehicle control device, a method for producing an LC module and a corresponding motor vehicle control device with an electrolytic capacitor module. The electrolytic capacitor module includes a cylindrical electrolytic capacitor with a capacitor can and a cover at each end of the can. The covers secure a capacitor winding inside the capacitor can. The electrolytic capacitor module also has a support plate with a chamber for accommodating the electrolytic capacitor. The capacitor can has at least one opening and, on the inside of the electrolytic capacitor, the interstice between the inner wall of the capacitor can and the capacitor winding is at least partially filled with casting compound. The capacitor is at least partially surrounded by the same casting compound on the outside thereof in the region of the chamber.

Abstract: A device for controlling and regulating a DC voltage converter. The device may have one or more power output stages and a control unit with a signal ground line. The one or more power output stages and the control line have a mutual ground potential. A switch for electrically disconnecting the signal ground line is provided. The switch is opened, when the DC voltage converter is active and the switch is closed, when the DC voltage converter is inactive.
