摘要： 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.

摘要： Usually, power supplies are not capable of switching off part of the outputs of a main power supply during stand-by. Due to this, stand-by power supplies are used in addition to operation power supplies. According to the present invention, a forward converter is provided, including switches in the rectifier circuit thereof. Due to this, the rectifier circuits may be selectively switched on and off. Advantageously, this may allow that the main outputs of such a forward converter are switched off while on stand-by.

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.

摘要： The invention relates to a circuit arrangement for a converter (1) with switches (S1, S2) for chopping a DC voltage U1 into a chopped DC voltage U3, comprising control means for controlling the switch-on times of the switches (S1, S2), in which switch-on times of the switches (S1, S2) alternate with each other and are separated from each other by dead-time phases Ttot, and circuit elements comprising a resonant circuit having at least one capacitor (Cr) and at least one coil (Lr) for converting the chopped DC voltage U3 into an output voltage U2. To ensure a reliable and interference-free ZVS operation of such a circuit, a circuit arrangement and a method of operating such a circuit arrangement are proposed in which a value for the energy/charge remaining in the resonant circuit for switching the switch in the inductive mode of operation is determined and compared with a threshold value by means of a comparator (24), and in which the switches (S1, S2) are controlled in dependence upon the comparison result.

摘要： Recently, the use of class - D audio amplifiers has become more and more widespread. In contrast to the generally employed class - AB linear amplification technology, class - D allows for improved efficiency. However, the class - D principle is known for its poor distortion characteristics. According to the present invention a digital amplifier (18) is provided for converting an audio signal to a power output, comprising a ripple suppression circuit (16) for suppressing voltage ripples in a supply voltage supplied to the bridge circuit with (6) at least one pair of switches. The ripple suppression circuit (16) suppresses ripples in the supply voltage supplied to a switch in the bridge circuit (6), which has been found to cause a major part of the distortions in the output signal of the digital amplifier (18).

摘要： The invention relates to an illumination device for embedding data symbols of a data signal into a luminance output of the illumination device. The device includes a LED comprising at least two segments which have a common electrode and are individually controllable. The LED is configured to generate the luminance output in response to a drive signal. The device further includes a controller configured for switching one of the segments on or off in response to the data signal to embed data symbols of the data signal into the light output of the device. One advantage of such an approach is that the proposed device is compatible with conventional LED drivers since no additional electronics for modulating the drive signal are necessary, which enables simple implementation and reduced costs.
