    • The invention relates to a device for controlling power by phase control of an alternating voltage supplying an electric consumer (14) and for reducing harmonic waves resulting from the phase control, particularly up to a range of 4 kHz, preferably in the range of the third harmonic wave. Said device comprises a first circuit element (12) (TRIAC), which is connected in series to the consumer (14) and which is controlled by a control device (20) in order to execute a phase control. The device is characterized in that a second circuit element (34) is connected in series to a resistor element (32), whereby the series connection is situated parallel to the first circuit element (12). The control device (20) is configured in such a manner that it controls the second circuit element (34) shortly before the first circuit element (12) and, for a short duration, switches it into the conducting state. The invention also relates to a method for reducing harmonic waves in the range of up to 4 kHz, preferably the third harmonic wave, during a power control involving phase-control.

    • A fan cooler for electric or electronic sub-assemblies has a control circuit with a control stage for controlling the speed of rotation of a fan motor connected to the control stage depending on set values. To achieve a polyvalent operation with a simple design, the fan motor is a phase-controlled asynchronous motor, the control circuit has a micro-controller that controls the control stage, an optic coupler is connected between the control stage and the micro-controller, and the micro-controller determines the operating angle for controlling the fan motor on the basis of the set values and the zero crossing of a control signal.

    • An electronic controller for an electric hand tool for use in screwing and drilling is disclosed, which comprises a phase shift controller, or a pulse width modulator. The electronic controller is operated by the control element of the tool switch and the corresponding potentiometer. The programme of the electronic controller is arranged, such that, during the beginning of hammer drilling operation, a pulse-like rotation style at a low and jerky speed is obtained and, from a certain position of the control element onwards, the further operation of the hammer drilling process occurs with a variable continuous speed. During the screwing operation, a continuous speed is initially available and, from a certain position of the operating element onwards, the further screwing process occurs with a pulse-like, lightly jerky rotation style of the electric hand tool. With full activation of the control element of the tool switch a strongly jerky rotation style with a very high torque occurs.
