Abstract
A supply line structure for supplying energy to electrical components of a motor vehicle, and for the transmission of information between at least a portion of the components (so-called Powerline Communications). To improve the channel characteristics of the information transmission via the supply line structure, it is proposed that the supply lines be arranged in a star configuration having at least one star point, the or each star point an impedance which corresponds to the characteristic impedance of the individual supply line branches running into it. To that end, it is proposed in particular that at the or each star point, an additional series resistor, frequency-dependent for frequencies below 100 MHz, be disposed in the incoming supply line branches. The series resistor is preferably configured as a ferrite sleeve.
