摘要： The invention relates to an image projector with a High-Intensity-Discharge HID lamp (112) and a method of operating it. Such lamps have the disadvantage that their voltaic arc jumps back and forth between different positions at unforeseeable times during operation. This so-called arc jumping has the effect of changing the brightness, i.e. the overall brightness and/or the brightness distribution of the light emitted by the HID lamp (112). For the viewer of an image projected with such a projector, this effect appears as a jolt of this projected image. To avoid such effects for the viewer, it is first proposed according to the invention that changes in the brightness of the light in the image projector's beam path are detected. As soon as a change in brightness caused by an arc jump has been detected, this brightness is reset to a brightness detected at a moment t-2 before the arc jump, in order subsequently to convert it during a predetermined time interval T to the brightness resulting from the arc jump. This resetting must occur so soon after the arc jump, and the conversion so slowly, that the changes in the brightness of the light incident on a picture screen device (118) resulting from the arc jump, the reset, and the conversion are not perceptible to the human eye.

摘要： The present invention relates to a bidirectional semiconductor switch (M1, M2) with extremely low control power consumption and a bootstrap circuit which allows reliable start of operation of the switch and the hosting device after unlimited duration of mains interruptions. Intelligent control options are provided by operating from a small energy storage and no extra means are required to recover from a depleted energy storage condition. The absence of audible noise and mechanical wear also enables more frequent recharging cycles and allows smaller and thus cheaper energy storage components.

摘要： Driver circuits (1) for driving load circuits (2, 3) receive source signals from sources and provide feeding signals to the load circuits (2,3) and charging signals to capacitor circuits (21). These capacitor circuits (21) provide supporting signals to the load circuits (2, 3) in addition to the feeding signals. By providing the driver circuits (1) with control circuits (22) for controlling the supporting signals, the capacitor circuits (21) can become less bulky/costly and/or will limit the lifetime of the driver circuits (1) to a smaller extent. Further, these driver circuits (1) may get improved efficiencies. Said controlling may comprise controlling moments in time at which the supporting signals are offered to the load circuits (2, 3) or not, and/or may comprise controlling sizes of the supporting signals, and/or may be done in response to detection results from detectors (23) for detecting parameters of one or more signals. Said controlling may comprise switching via switches (24).

In this method an operating frequency of the lamp is switched from a first frequency value (fi) to a second frequency value (f2), which second frequency • (f 2) value is higher than the first frequency value (fi)′, if a first time criterion pertaining to a duration of driving of the lamp (1) in the second operation mode (OMn) is fulfilled and the operating frequency is switched from the second frequency value (f2) to the first frequency value (fi), if a second time criterion pertaining to a duration of driving of the lamp (1) in the first operation mode (OMP) is fulfilled.

摘要： A wireless resonant powering device 1 according to the invention comprises a first inductor winding 3, which is arranged to form a transformer 9 with the inductor winding 13 of the energizable load 11. The first inductor winding 3 is arranged to form a resonant circuit 5, which may comprise a suitable plurality of electric capacitances and coils. The components of the resonant circuit 5 are selected such that the magnetic energy received by the inductor winding 13 damps the energy flow in the resonant circuit so that the induced voltage in the inductor winding 13 is substantially constant and is independent of the magnetic coupling between the first inductor winding 3 and the inductor winding 13 at the operating frequency of the driving means 6. The resonant circuit is driven by the driving means 6, comprising a control unit 6c arranged to induce an alternating voltage between a first semiconductor switch 6a and a second semiconductor switch 6b. At the output of the transformer 9 an alternating voltage is generated, which is rectified to a DC-voltage by a diode rectifier, filtered by an output capacitance. The resonant circuit 5 is operable on its coupling independent point by the driving means 6. This figure schematically illustrates a situation, where a variable coupling between the first inductor winding 3 and the inductor winding 13 exists. The invention further relates to a wireless inductive powering device, an energizable load, a wireless system and a method for wireless power transfer.
