  • Patent number: 10341124
    Abstract: The invention relates to a power distribution system comprising a power providing device (3) for providing power and a powered device (4, 5, 6) like a luminaire to be powered by the power providing device. The power providing device and the powered device are operable in a maximum power mode and a normal operation mode, wherein in the maximum power mode the powered device consumes an amount of power maximally consumable by the powered device and the power providing device measures the power consumed by the powered device. This measured power allows for an allocation of an amount of power in the operational mode, which is really maximally needed, wherein it is not necessary to allocate a larger amount of power, which is large enough to consider, for instance, a maximally assumed length of an electrical connection (8) connecting the devices, thereby improving the power budget allocation.

  • Patent number: 10216255
    Abstract: The invention relates to a power distribution system, such as a Power over Ethernet power distribution system. A powered device provides a pulse, such as a Maintain Power Signature, when in standby such that a power providing device remains providing power to it. To increase energy efficiency, the MPS can be cycled (60 ms pulse every 300 ms to 400 ms) according to the IEEE802.3af/at standards. By introducing a controllable switch, for electrically decoupling at least part of the powered device from the power providing device, and a pulse generator, the MPS can be generated in a more energy efficient way and/or can be shortened (e.g. to 5 ms). As an example, the controllable switch can decouple the bulk capacitor of the powered device during MPS generation to prevent the bulk capacitor from filtering out the MPS.

  • 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.
