摘要： 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.

摘要： The invention relates to a power converter comprising an inductor 6 for receiving energy from a power supply 1, and connected to the inductor 6 an output capacitor 7 for providing an output voltage. In order to ensure a quick compensation of a reduction of load at the voltage output using few output capacitors, it is proposed that an additional current path 11,12 is arranged in parallel either to the inductor 6 or to the capacitor 7, which additional current path 11,12 can be opened and closed. A current flowing through the additional current path 11,12 reaches basically immediately a desired value, when the additional current path 11,12 is opened. Feedback means are moreover provided for opening the additional current path 11,12, when the output voltage reaches a predetermined maximum value. The invention relates equally to a corresponding method.

摘要： The trend towards more digital signal processing in mains-powered devices causes an increasing variety of supply voltages at ever decreasing levels and at higher currents. At present, the secondary side architecture provides a separate ac-dc conversion and dc-dc down-conversion stages in order to obtain stabilized voltages at those low levels. According to the present invention, a controlling synchronous rectifier is provided, comprising a power MOSFET and a control unit which allow to integrate both stages. In particular, according to the present invention, the output voltage of the synchronous rectifier is controlled by controlling the channel switching of the MOSFET. Advantageously, this provides for a very simple and efficient rectification and voltage control.

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.
