Abstract
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.
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.
Claims (3)
