Abstract: The invention relates to a method and a device ( 1 ) for data transmission in a power supply network (power line communication). The device ( 1 ), preferably centrally located in a distribution box ( 6 ), is equipped with transceivers ( 3, 4, 5 ), each one of which is connected to a phasing line ( 11, 12, 13 ) of the power supply network, from which it can receive data, and to which it can transmit data. The transceivers are coupled via a control unit ( 2 ), wherein the control unit ensures that the data received from a phasing line can be transmitted, prepared, on at least one other phasing line. Hereby, a re-transmission on all phasing lines with the same transmission power, or a re-transmission matched to the particular signal strengths or the addressees of the data, can take place.

Abstract: The invention relates to a method and a server ( 1 ) for implementation of central standby functions in an (in-home) network with devices ( 11 - 16 ) connected thereto. The standby server ( 1 ) contains a central processor ( 3 ), a mass memory ( 4 ) and interfaces ( 2, 5, 6 ) for the network connection. When one of the devices ( 11 - 16 ) is shut down, it sends corresponding information and where applicable data to the server ( 1 ) whereupon the latter takes over the standby functions for the device. In particular the server ( 1 ) can temporarily store data directed to the device as long as this is switched off, or pass on with time delay data to be transmitted by the device. Centralization of the standby functions in a special server reduces the energy consumption and improves the speed of data transmission.

Abstract: The invention relates to a coupling module ( 1 ) via which communication becomes possible between different electronic appliances of an (in-home) network ( 30 ). To this end, the coupling module ( 1 ) can be expanded in modular fashion with transmitter and receiver modules ( 20 - 27 ), which in each case create a network interface with the electronic appliances, with the associated transmission protocol in each case. The coupling module ( 1 ) may preferably independently detect the connected appliances, and pass on incoming information to the particular addressee in the appropriate protocol.

Abstract: In the case of known switched-mode power supplies with integrated preconditioner, the control curves are largely congruent, but deviate from one another in low-load operation, whereby the unregulated intermediate circuit voltage increases. To improve efficiency in low-load operation, closed-loop control of the burst cycle is effected on the primary side of the voltage transformer. The intermediate circuit voltage is limited to a permissible limit value. The closed-loop control device in the switching stage taps the intermediate circuit voltage at a voltage divider which is arranged between the preconditioner functional unit and the switching stage. An assembly additionally monitors the output voltage, for example by means of an optocoupler. Burst mode comprises one or more burst cycles. A burst cycle is started when the intermediate circuit voltage reaches its limit value. At this time, the voltage transformer is switched off. A burst cycle ends when the output voltage reaches a minimum value. At this time at the latest, the voltage transformer is switched on again. Burst mode is terminated again either when the switched-mode power supply is again operated under normal load or when a maximum time has elapsed, measured from the start of burst mode.
