  • ASYMMETRIC OVERVOLTAGE PROTECTION APPARATUS, DC CIRCUIT ARRANGEMENT AND DC NETWORK
    Publication number: 20220224110
    Abstract: An asymmetric surge protection device for a DC circuit (16) has a negative side (32) which can be connected to a current output (28) of the DC circuit (16), a positive side (30) which can be connected to a current input (26) of the DC circuit (16), and an asymmetric neutral section (34). The asymmetric neutral section (34) has a positive protection level (Vp) for a positive voltage (V) between the positive side (30) and the negative side (32), and a negative protection level (Vn) for a negative voltage (V) between the positive side (30) and the negative side (32), the positive protection level (Vp) being different from the negative protection level (Vn). Furthermore, a DC circuit arrangement (14) and a DC network (10) are shown.
