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.

Claims (3)

1. Apparatus for controlling the power of an AC voltage sup-plying an electrical consumer (14) by phase control and for reducing harmonics caused by said phase control, par-ticularly within a range of 4 kHz, preferably within a range of the third harmonic, comprising a first switching element (12) (TRIAL) connected in series with said con-sumer (14) and driven by a control device (20) for per-forming a phase control, characterized in that a second switching element (34) connected in series with a resistor element (32) is provided, said series connection is pro-vided electrically parallel to the first switching element (12), and said control device (20) is adapted such that it drives the second switching element (34) shortly before the first switching element (12) and switches it in its conducting state for a short time period.
2. Apparatus of claim 1, characterized in that the second switching element (34) is a TRIAL.
3. Apparatus of claim 1 or 2, characterized in that the re-sistor element (32) is an ohmic resistor.
