Abstract:
1. A supply line structure for supplying energy to electrical components of a motor vehicle and for transmitting information between at least a portion of the electrical components, comprising: supply lines arranged in a star configuration having at least one star point, the at least one star point exhibiting an impedance corresponding to a characteristic impedance of individual supply line branches running thereinto, wherein each supply line is used to transmit both energy and information across a single wire; wherein an additional series resistor is arranged at the at least one star point in each of the individual supply line branches; wherein the additional series resistor is frequency-dependent below a frequency of 100 MHz, whereby at a frequency of 0 Hz, the additional series resistor has a resistance value of substantially 0 ohm, and in a frequency range above 100 MHz for transmission of information via a supply line, the additional series resistor has a resistance value of Z wherein a value of the additional series resistor at the at least one star point is yielded by the equation: with a reflection factor r* star and a number n of individual supply line branches having a character impedance Z L feeding into the at least one star point, wherein n is greater than or equal to two, the reflection factor (r* star ) being yielded at one of the individual supply line branches in which an incoming wave is running, and by consideration of the additional series resistor, Z series , in the one of the individual supply line branches.
