Publication number: 20190229526Abstract: A device for coupling a control unit with a voltage supply. An electrical connection between the voltage supply and the electrical control unit may be opened/closed with a switching element. An electrical resistor, which allows for a limited current flow from the voltage supply to the electrical control unit even when the switching element is open, is parallel to the switching element. Thus, an electrical energy store, such as a capacitor or a similar device, which is to buffer the input voltage at the electrical control unit, is chargeable even when the switching element is open. This is to avoid adverse effects caused by the charging of a capacitor at the input of the control unit when the switching element is closed.Type: ApplicationFiled: August 15, 2017Publication date: July 25, 2019Inventors: Alexander Hey, Fabian Wingert, Martin Buecker, Oda Limbach, Simon Riedel, Stefan Hoess, Thomas Saile, Volker Weeber
