摘要： The invention specifies an arrangement with a voltage converter (1) for supplying power to an electrical load (2) having a current sink (3), a prediction unit (5) and a comparator (6) and also an associated method. The voltage converter (1) can be connected to a voltage source and drives a series circuit which comprises a means for connecting the electrical load (2) and the current sink (3). The voltage at the output of the voltage converter (1) has a dependency on a multiplication factor. The prediction unit (5) ascertains a predicted current sink voltage, that is to say the voltage dropping across the current sink, for a new multiplication factor. The comparator forwards the new multiplication factor to the voltage converter if the predicted current sink voltage is higher than a prescribeable threshold value. The arrangement described is particularly well suited to supplying power to light emitting diodes.

摘要： A method includes a voltage converter outputting an output voltage that is based on an input voltage and on a first multiplication factor, determining a predicted current sink voltage based on a new multiplication factor obtained from a set of selectable values, based on a signal derived from the input voltage, based on a load voltage across an electrical load, and based on a correction voltage. The method also includes comparing a predicted current sink voltage with a predetermined threshold value and outputting the new multiplication factor to a control input of the voltage converter if the predicted current sink voltage exceeds the predetermined threshold value.

摘要： An apparatus and a method for charging and for charge monitoring of a rechargeable battery. A charging circuit contains a rechargeable battery (B) and a charging device (L) for charging the rechargeable battery. A measurement device (M) is arranged in the charging circuit and contains a device for determining the rechargeable-battery current and the state of charge of the rechargeable battery. A control device (R) compares a value that is proportional to the rechargeable-battery current with a set value, and controls the charging device.
