Embodiment Construction

[0038] In the drawings, the same or similar elements are indicated by the same reference signs. The drawings are only schematic representations, and are not intended to depict specific parameters of the invention. In addition, the drawings are only intended to describe typical embodiments of the present invention, and therefore, should not be regarded as limiting the scope of the present invention.

[0039] figure 1 A preferred embodiment of the switch module 10 according to the present invention is schematically described. The switch module 10 is connected to at least two conductor segments 102a, 102b of a power supply network (not shown), which includes one or more power sources (not shown) and one or more electrical loads (not shown).

[0040] The switch module 10 includes a switch 12 and a control unit 20 for controlling the switch 12. The current sensor 14 at one of the two ends of the switch 12, the voltage sensor 16 at one end of the switch 12 (hereinafter referred to as “...

Abstract

The invention relates to a switch module (10; 10a...10f) comprising at least one switch (12) exhibiting at least two states of operation, provided for connecting at least two conductor segments (102a, 102b) of an electrical power supply network (100), the electrical power supply network (100) comprising one or more power sources (104, 106) and one or more electrical loads (110... 114). One control unit (20) is provided per switch (12) and is operatively coupled to said switch (12) for controlling said states of operation of said switch (12). Each control unit (20) comprises a selection unit for selecting a state of operation of the switch (12) coupled to the respective control unit (20). The invention relates also to a method for operating such switch modules (10a...10f) and an electric power supply network (100).

Description

Technical field [0001] According to the preamble of the independent claim, the invention relates to a switch module for a power supply network and a power supply network comprising at least one switch module. Background technique [0002] Especially in vehicles of the future technology, redundant power supply systems are required in several subsystems. The obvious application is safety-critical systems such as braking, steering, etc. There are other systems that affect the real-time behavior of the vehicle, such as chassis control, etc., powertrain components such as valves, etc., electronically controlled gearboxes, and so on. Some of today's mechanical components may rely entirely on electronic control. Electronic failure can cause mechanical failure. [0003] In the prior art, a typical automotive power supply network is known to be provided in a star structure or a daisy chain structure. A short circuit at any point in this type of structure will stop the entire network dow...
