摘要： An amplification device is disclosed providing a way of integrating a switch mode power supply and a class D amplifier (switch mode amplifier). This results in the usage of basically one magnetic component (1), one major energy storage element (4) and switches (20, 30) that are controlled in such a way that both the power supply function and the amplification function are achieved. In this way a cheap, small and highly efficient current configuration is achieved. This amplification device is especially useful in audio products.

摘要： A voltage regulating circuit comprising a rectifier (2) for receiving an AC voltage (Vmains) and for generating a rectified AC voltage (vrec), and a capacitor (3) connected in parallel with said rectified AC voltage for providing a DC voltage (VDC) over a load (5), characterized by a unidirectional current switch (4) provided between the rectifier (2) and the capacitor (3), and a control block (6) arranged to activate the switch (4) at selected instances (7) during negative slopes of the rectified AC voltage (vrec) so that said DC voltage (VDC) does not exceed a predetermined voltage limit. By controlling the voltage provided by the rectified mains, the DC voltage can be regulated to any preset value (lower than the AC mains peak value). The inventive voltage stabilizer will guarantee a desired constant DC load voltage value for different mains peak input voltages and under wide range of load variations. Thereby a converter driven by this voltage can be more optimized or even be unregulated.

摘要： A buck converter, boost converter or flyback converter is generally represented as a two-port having a primary side with a primary switching device (10; 38; 70; 98; 110), and a secondary side with a secondary switching device (20; 50; 80; 106). The primary switching device is controlled in such a way that the on-time is adapted to the voltage at the primary side of the converter. The relation between the on-time of the primary switching device and the primary voltage is a generally hyperbolic function.

摘要： The present invention relates to a multiple output flyback converter having a switch regulated output circuit (5). To avoid a second communication interval, due an output voltage in this secondary controlled output that is lower what is implied by its number of winding turns, the inductance of this circuit is increased. This can preferably be done by increasing the leakage inductance of the winding (6) in the regulated circuit.

摘要： The invention relates to a transformer (10, 10′) with a core (11) which has a center piece (11a) with a first and a second flange (11b, 11c), in which a first and a second winding (12, 13) of the transformer (10, 10′) are wound on the center piece (11a).To produce a transformer as compact as possible which allows simple adaptation to limit leakage currents, it is proposed that the winding end pieces (12a, 12b) of the first winding (12) guided out of the winding body are guided through at least one recess in the first flange (11b) and that winding end pieces (15a, 15b) of the second winding (13) guided out of the winding body are provided which form at least partly loose line ends. Alternatively, the winding end pieces (12a, 12b) of the first winding (12) guided out of the winding body are guided immediately about the edge of the first flange (11b) and connected with connecting elements (14a, 14b) which are arranged on the side of the first flange (11b) opposite the center piece (11a).

摘要： A switch mode power supply for feeding a single ended class D amplifier, having. two voltage sources (1, 2) is disclosed. The power supply comprises a voltage equalizer circuit including a coil (10) having a first terminal connected to said common point (3), a first switch (11) connected between a second terminal of the coil (10) and the positive side of the first source (1), a second switch (12) connected between said second terminal of the coil (1) and the negative side of the second source (2), and control circuitry (13, 14) for determining when the voltage (v 1, v2) of one of the voltage sources (1 or 2) exceeds a predetermined threshold value (vthresh,ON), and, in response to such a determination, periodically operate the switch (11 or 12) associated with said one voltage source ON and OFF, thereby redistributing energy from said one voltage source (1 or 2) to the other voltage source (2 or 1). The inventive voltage equalizer thus acts as a switch mode converter, redistributing energy from one voltage source to the other, thereby ensuring that the output voltages of both sources are essentially equal. Further, the voltage equalizer requires very few components, and is thus simple to implement. As the two switches only need to handle the excess of power they can be relatively small and cost efficient.

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： According to one example embodiment, a power-supply system describing a bi-directional flyback topology includes two flyback converters working in opposite directions. Current flowing from a power supply unit to an apparatus is converted from a mains input in the power supply unit to a rectified output current fed to the apparatus via a two-lead cable. In the opposite direction, a secondary control circuit, situated in the apparatus, including a secondary switch causes excess current to be fed back to the power-supply unit where primary control circuitry reacts to stabilize the current fed to the apparatus. The primary control circuitry serves to minimize the amount of energy received from the feedback. The excess current in the apparatus is determined by monitoring the voltage and the current in the apparatus is load. If the measured parameters are too high, transfer of more energy back to the power-supply unit will be performed.

摘要： A multimode switched-mode power supply operates in a first control mode when the output power supplied is lower than a predetermined value, and in a second control mode when the output power supplied is higher than said predetermined value. The switched-mode power supply comprises a series arrangement of a switch (S1) and an inductor (L; Lp), the series arrangement being coupled to receive a DC input voltage (Vin). A control circuit (CC) controls the on and/or off times of the switch (S1) to generate a periodical inductor current (Ip) in the inductor (L; Lp). In the first control mode, a peak value of the inductor current (Ip) is substantially constant, independent of the power supplied. The substantially constant peak value is substantially equal to a peak value of the inductor current (Ip) at an instant when the second control mode is altered into the first control mode.
