Abstract (en)

[origin: EP1124299A1] A power supply unit consisting of a decentralized power supply device for a bus (1) which routes information and power for electrical distribution systems for bus coupling units (1) and bus devices (2). A compensating pulse is respectively generated in between two initial pulses in order to obtain a direct voltage which in sum is as constant as possible. Bus devices for application functions can be connected to interfaces of the bus coupling units. The power supply unit is designed for active current-limiting and for decoupling in order to enable parallel arrangement of several power supply units. An energy storage mechanism (C,C1) is provided in order to store energy between two initial pulses. According to the invention, the decentralized power supply device is respectively arranged in a power supply unit (3) which is designed for active current-limiting, and a transmission module (4) serving several power supply units (3) is provided for the generation of compensating pulses and is fitted with said energy storage mechanism.
