Abstract

The electrical signal is generated in particular for use in controlling the illumination level of a lamp (10). The electrical signal (V4, 5) is generated as a hybrid combination of two voltage signal portions that are generated from two sinusoidal forms. The first sinusoidal form is the mains signal that could have a frequency at 50Hz or 60Hz (12). The second sinusoidal form is the result of an oscillating stage (16) that creates the sinusoidal form to have a much higher frequency than the mains frequency, such as 100kHz (V2). The first signal portion is generated following application of a biasing signal (V2) switching device such as a FET (14). The second signal portion is generated by application of a gating signal (V3) to a gating device such as a triac (11).
