Abstract (en)
[origin: WO2020104275A1] The invention relates to a reflection damping device (50; 50 A; 50B; 50C; 50D; 50E; 50F; 50G; 50H) for a bus (40) of a bus system (1) and to a method for damping reflections during data transmission in a bus system (1). The reflection damping device (50; 50 A; 50 B; 50C; 50D; 50E; 50F; 50G; 50H) can close a free end of bus lines (41; 42) of the bus (40), in particular in a transceiver (12; 22; 32) of a subscriber station (10; 20; 30) of the bus system (1). Alternatively, the reflection damping device (50; 50 A; 50B; 50C; 50D; 50E; 50F; 50G; 50H) can be connected to a branching point of the bus (40) which is in particular a star point or is intended to connect a subscriber station (10; 20) to the bus (40). As a result, bus subscribers in a vehicle trailer can also be connected, as required, to the bus system (1) of the vehicle. The reflection damping device (50; 50 A; 50 B; 50C; 50D; 50E; 50F; 50G; 50 H) comprises at least one pair (51; 52; 51A; 52A; 51 B) of electrical semiconductor components connected in parallel, and at least one capacitor (53; 54) which is connected in series to the at least one pair (51; 52; 51A; 52A; 51B) of electrical semiconductor components connected in parallel, for damping reflections on a bus line (41; 42) of the bus (40).
