  • Patent number: 10148088
    Abstract: The invention relates to a power distribution system for distributing power from a power supply (2) to several electrical loads (4, 5) via sockets (3). The sockets receive power requests from the electrical loads and transmit the power requests to a master device (9) which controls the power to be provided by the respective socket based on the received power requests. Since the master device receives all power requests from the sockets and has therefore an overview of the overall power requirements, the master device can determine the power to be provided by the respective socket under consideration of this knowledge. This can lead to an improved determination of the power to be provided by the respective socket and hence to an improved overall power distribution.
