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： 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.

摘要： An electrical circuit arrangement provides a low power rectified low voltage from an AC line voltage. The circuit consists of two circuit blocks combined together via an intermediate circuit, of which the first circuit block contains a capacitive input stage for producing a voltage-limited intermediate voltage that is substantially less than the line voltage, and a second circuit block that contains an asymmetric half-bridge that receives the intermediate voltage and produces an AC voltage that is decoupled from the line voltage via a transformer that is operated at the substantially lower voltage. The output of the transformer is rectified to provide the low-level DC output.

摘要： The system 1 according to the invention comprises an energizable load 2 and an inductive powering device 9 and 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 serves for an instant proper mutual alignment of the winding 6 and further winding 9b. The invention further relates to a inductive powering device, an inductive load and a method for enabling an inductive energy transfer to en energizable load.

摘要： A power supply arrangement having a DC/DC converter is presented that includes a control loop on the primary side of the isolation transformer within the DC/DC converter to control the voltage on the primary winding. The energy transfer across the isolation transformer is effected via control switches that alternately charge and discharge a capacitor through the primary winding. The control loop preferably adjusts the duty cycle of these control switches to control the voltage on the primary winding.
