摘要

The invention relates to a HV vehicle electrical system, the HV vehicle electrical system (1) comprising a high-voltage source (2), a central intermediate circuit capacitor (3) and at least two high-voltage components (4, 4a, ..., 4g), the positive pole connections of the high-voltage components (4, 4a, ..., 4g) are each connected to the positive pole connection of the central intermediate circuit capacitance (3) and the negative pole connections of the high-voltage components (4, 4a, ..., 4g) are each connected to the negative pole connection of the central intermediate circuit capacitance (3). where connections of the central intermediate circuit capacitor (3) and the connections of at least one of the high-voltage components (4, 4a, ..., 4g) are electrically connected via a low-inductance conductor arrangement (7) whose inductance per unit length is less than 0.2 µH/m , wherein this at least one high-voltage component (4, 4a,..., 4g) is electrically connected to the central intermediate circuit capacitance (3) in such a way that one of a connection capacitance of the high-voltage component (4, 4a,..., 4g) and a connection capacitance of the electrical connection between the high-voltage component (4, 4a,..., 4g) and the central intermediate circuit capacitance (3) resulting capacitance is less than or equal to 100 μF and a method for producing a such a high-voltage vehicle electrical system.
