| Zusammenfassung: | Disclosed is an on-board power supply system and a protection method for protecting an on-board power supply system. The system comprises:
a first power supply terminal (1) and a second power supply terminal (2) configured to have a battery (11) and/or a generator (13) connected thereto;
a first external terminal (31) coupled to the first power supply terminal (1) and a second external terminal (32) coupled to the second power supply terminal (2); and
a protection unit (40) connected between the first external terminal (31) and the first power supply terminal (1),
wherein the protection unit (40) comprises:
a semiconductor switching unit (41) having a load path and a control terminal, the load path connected between the first external terminal (31) and the first power supply terminal (1); and
a control circuit (42) coupled to the control terminal of the semiconductor switching unit (41) and configured to switch the semiconductor switching unit (41) on and off dependent on at least one electrical parameter in the on-board power supply system. |
