LIGHTING SYSTEM INCLUDING A MULTI-PHASE INTERLACED POWER CONVERTER

摘要

The invention relates to a lighting system (1) of a motor vehicle comprising: a light source (2), a multi-phase interlaced type power converter (3) comprising several elementary converters (31a, 31b, 31c, 31n) selectively activatable, each elementary converter being arranged to generate an electrical signal (Ia, Ib, Ic, In) having a proper phase, the power converter being arranged to supply an electrical power (Ps) to said light source; and a controller (4) arranged to selectively control each of the elementary converters of said power converter; characterized in that the controller is arranged to receive an instruction to transmit (Im) a desired light beam by the light source and to activate a strictly necessary number (N) of elementary converters of the power converter so that the power converter supplies the light source with the necessary electrical power (Pn) for the emission of said desired light beam.
