Abstract:
1. A power supply of luminous sources, comprising: first means for generating a direct voltage signal starting with an alternating input voltage; second means for inputting said direct voltage signal and being for generating an alternating voltage signal of rectangular wave shape and null average value; third means for generating a current signal of triangular wave shape from the alternating voltage signal of rectangular wave shape and null average value; fourth means for extracting from said current signal of triangular wave shape a voltage signal of triangular wave shape and non-null average value; fifth means for controlling the frequency of the alternating voltage signal of rectangular wave shape and null average value in function of an average value of the voltage signal extracted by said fourth means; and sixth means for rectifying said current signal of triangular wave shape coming from said third means and for supplying the luminous sources.
