    Abstract: The invention relates to a power converter comprising an inductor 6 for receiving energy from a power supply 1, and connected to the inductor 6 an output capacitor 7 for providing an output voltage. In order to ensure a quick compensation of a reduction of load at the voltage output using few output capacitors, it is proposed that an additional current path 11,12 is arranged in parallel either to the inductor 6 or to the capacitor 7, which additional current path 11,12 can be opened and closed. A current flowing through the additional current path 11,12 reaches basically immediately a desired value, when the additional current path 11,12 is opened. Feedback means are moreover provided for opening the additional current path 11,12, when the output voltage reaches a predetermined maximum value. The invention relates equally to a corresponding method.

    Abstract: The invention describes a method of shutting down a high pressure discharge lamp (1) in which a pair of electrodes (2) is disposed in an arc tube (3), which method comprises reducing, upon receipt of a shut-down request (SR), the lamp power (P) towards a reduced power level (PR) required to sustain a long-term arc discharge between the electrodes (2), and driving the lamp (1) towards the reduced power level (PR) for a reduced power duration before completely shutting down the lamp power (P), whereby, prior to reducing the lamp power (P) towards the reduced power level (PR), the lamp power (P) is reduced to an undershoot power level (Pu), which undershoot power level (Pu) is lower than the reduced power level (PR) required to sustain a long- term arc discharge between the electrodes (2), and the lamp is driven at this undershoot power level (Pu) for an undershoot power duration (tu) before increasing the lamp power (P) again to approach the reduced power level (PR). Moreover the invention describes an appropriate driving unit (4) for driving a high pressure discharge lamp (1) and an image rendering system (40), particularly a projector system, comprising such a driving unit (4).

    Abstract: The system (1) according to the invention comprises an energizable load (2) and an inductive powering device (9) as well as a permanent magnet (8) arranged on the conductor (4) for interacting with the further conductor (9a) for aligning the inductor winding (6) with respect to the further inductor winding (9b). The energizable load (2) for enabling the inductive power receipt comprises a wiring (6) which cooperates with the conductor (4) for forming a secondary wiring of the transformer. In order to form the system for inductive energy transfer, the energizable load (2) is to be placed on the inductive powering device (9), whereby the surface (2a) will contact the surface (7). The inductive powering device (9) comprises a further magnetizable conductor (9a) provided with a further winding (9b), thus forming a primary wiring of the split-core electric transformer. When the winding (6) is brought in the vicinity of the further winding (9b), the magnetic force acting on the further magnetizable conductor (9a) provides for instant proper mutual alignment of the winding (6) and further winding (9b). The invention further relates to an inductive powering device, an inductive load and a method of enabling an inductive energy transfer to an energizable load.

    Abstract: The trend towards more digital signal processing in mains-powered devices causes an increasing variety of supply voltages at ever decreasing levels and at higher currents. At present, the secondary side architecture provides a separate ac-dc conversion and dc-dc down-conversion stages in order to obtain stabilized voltages at those low levels. According to the present invention, a controlling synchronous rectifier is provided, comprising a power MOSFET and a control unit which allow to integrate both stages. In particular, according to the present invention, the output voltage of the synchronous rectifier is controlled by controlling the channel switching of the MOSFET. Advantageously, this provides for a very simple and efficient rectification and voltage control.

    Abstract: In known converter circuits switching losses occur, which are caused by reverse-recovery currents of a freewheeling diode. To reduce said switching losses it is proposed by the invention to drive the switching elements such that, upon switching from the second to the first switching element, the timing is controlled in such a manner that the shoot through currents and the conduction of the freewheeling diode are kept at a low value or, better still, are precluded. As regards the control mechanism, it is proposed to turn on the first switching element later if shoot through currents occur, and to turn on the first switching element sooner if conduction of the freewheeling diode occurs. Here, a time of overlap may be provided during which both switching elements are simultaneously conducting. For the control mechanism, the voltage across a switching element can be used as a measured input value.
