摘要： The present invention relates to a multiple-output voltage converter. A basic idea of the present invention is to provide a multiple-output converter which may be adapted to various output power conditions. The converter has, in an exemplifying embodiment, three outputs which all share a common tapped inductor (301, 302). An inductor tap is employed to control the inductance of the inductor. A large inductance is used for low power standby operation and a small inductance is used when, for example, the LED backlight is switched on. Switches are arranged at the converter outputs to select to which one of the respective converter outputs the energy of the inductor is to be transferred.

摘要： Cables (1, 2) comprise first and second conductors (1, 2) for transporting signals to be picked-up in contactless manners. At first/second locations (3, 4), the first and second conductors (1, 2) are at first/second distances from each other. The first locations (3) are neutral locations where the conductors (1, 2) are parallel. The second locations (4) are pick-up locations. The second distances are larger than the first distances. Pick-up devices for picking-up signals in a contactless manner from the cables (1, 2) comprise parts for defining minimum values of the second distances. These parts may comprise core-parts, such as center ends (10) of E-shaped magnetic cores further comprising outer ends (11, 12) and backs (13). Methods for installing pick-up devices comprise steps of at second locations (4) increasing a distance between the first and second conductors (1, 2) from a value of the first distance to a value of the second distance. Twin-cables (1, 2) or twin-lead-cables (1, 2) are suited well for allowing signals to be picked-up in contactless manners.

摘要： 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.

摘要： The invention relates an electrical device for providing an output depending on an electrical input. The electrical device (1) is adapted to provide a constant output, if the electrical input is in a first electrical input range, and a dependent output, if the electrical input is in a second electrical input range, wherein the dependent output depends on the electrical input. The output can therefore remain constant, even if the electrical input, which is preferentially a DC grid voltage, fluctuates within the first electrical input range. Moreover, in the second electrical input range the output can be controlled by just controlling the electrical input like the DC grid voltage, without necessarily requiring an additional control construction of the electrical device. A resistance against fluctuations of the electrical input and a controllability of the output can therefore be realized in a relatively simple way.

摘要： A resonant matching circuit (310) for matching a resonant frequency of a wireless power transfer system to a frequency of a power signal comprises a switch (311) connected in parallel with a resonant element (302) of the wireless power transfer system; and a controller (312) connected to the switch (311) and configured to detect a zero-voltage level crossing of a signal flowing through the resonant element (302) and to close the switch (311) for a predefined amount of time upon detection of the zero-voltage level crossing, wherein closing the switch (311) for the predefined amount of time adds any one of an inductive value and a capacitive value to the resonant frequency of a wireless power transfer system.
