ABSTRACT:
A circuit arrangement and method for redundantly supplying current to a downstream load are provided. The circuit arrangement includes a first current path including a first switch element to which a first voltage is applied on the input side, a second current path including a second switch element to which a second input voltage is applied on the input side, a first control device which is connected to the first current path and used to control the first switch element, a second control device which is connected to the second current path and used to control the second switch element, and a common output terminal of the first and second current paths, from which a load supply voltage is emitted. In a normal operating state, the first control device holds the first switch element in a let-through state and the second control device holds the second switch element in a let-through state, and in an abnormal operating state, depending on electrical properties of the first current path or the second current path, the control device which is located in the current path having weaker electrical properties transfers the switch element in the current path into a blocking state.
