    摘要： In a method for controlling the strength of a charging current when charging a battery by means of an alternating voltage source, the rectified voltage of the alternating voltage source is fed to the battery via a phase control circuit with variable triggering angle. The battery voltage is measured and the value of the triggering angle to be set is identified as a function of the measured battery voltage and the voltage of the alternating voltage source.

    摘要： Disclosed is a circuit arrangement (10) for recognizing an undervoltage of an energy source (12). Said circuit arrangement (10) comprises a transistor switch (48) and at least one additional switching means (30). The inventive circuit arrangement (10) is characterized in that the transistor switch (48) and the additional switching means (30) have a low resistance in an operational state of the circuit arrangement (10) while the transistor switch (48) blocks the additional switching means (30) in order to interrupt the voltage supply when a supply voltage (U) of the energy source (12) drops below a defined voltage value (US).

    摘要： The invention relates to a battery-driven screwdriver comprising a housing (12, 18) provided with a handle (14), an on/off switch (26) and, particularly, a permanently fixed rechargeable battery (40) and charge contact tongues (37) which are associated with the rechargeable battery (40). The battery-driven screwdriver is characterised in that it is safe and comfortable to use due to the on/off switch (26) being mounted in a pivotable manner and extending in a longitudinal manner over the innerside of the handle (14), said on/off switch being able to be successively interrupted and/or closed, independently from each other, during the actuation stroke of several electric circuits of the battery-driven screwdriver (10).
