Abstract: Resonant gate driver circuits provide for efficient switching of, for example, a MOSFET. However, often an operation of the resonant gate driver circuit does not allow for an application where high switching frequencies are required. According to the present invention, a pre-charging of the inductor of the resonant gate driver circuit is performed. This allows for a highly efficient and fast operation of the MOSFETs.

Abstract: This invention describes a method for driving a gas discharge lamp (1), whereby an alternating voltage (U) is applied to the gas discharge lamp (1), the alternating voltage (U) having a first polarity during a first time interval (tfl, tsl) and a second polarity opposite to the first polarity during a second time interval (tf2, ts2). In this method, the first time interval (tfl) and the second time interval (tf2) are repeated alternately during a first operation mode. During a second operation mode, the electrical power (P) being provided to the gas discharge lamp (1) is smaller compared to the first operation mode, and the first time interval (tsl) and the second time interval (ts2) are repeated alternately, whereby in this second operation mode the duration of the first time interval (tsl) is at least a multiple of the duration of the second time interval (ts2). Furthermore, the invention describes an appropriate driving unit (4) for driving a gas discharge lamp (1), and an image rendering system, particularly a projector system, comprising a gas discharge lamp (1) and such a driving unit (4).

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.

Abstract: An increasing number of phases in multiphase converters causes an increase in requirements with respect to the control IC. According to the present invention, instead of deriving a new PWM signal for every single phase of the DC-DC converter, the single phases are clustered into groups (22, 24, 26). Within each group, the converters are operated on the basis of one PWM signal (PW M1, PW M2…PW MN). Advantageously, this may allow to reduce the requirements with respect to the control IC and thus may allow the application of cheaper and smaller control ICs.

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).

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).
