摘要： A device and a method for driving the supply of power to a plurality of light sources that is made up of a first group of light sources comprising at least one light source, which first group of light sources is connected in series with at least one second group of light sources comprising at least one light source. The device comprises a supply circuit to which the plurality of light sources is connected as a load. According to the inventive measures, it becomes possible to short at least one of the groups of light sources without causing high intensity transient current peaks in the light sources that are not shorted.

摘要： A device and a method for protecting the buck circuit of a DC voltage converter, for example of boost-buck type, if the input voltage of the boost circuit falls below a voltage threshold value. The invention finds a particular application in devices for controlling the power supply of light sources and notably light-emitting diodes (LED).

摘要： A device and method for controlling the supply of power to light sources, in which a DC/DC converter is capable of delivering a voltage VMAX to the light sources. The forward voltage of the light sources depends on temperature and may temporarily exceed VMAX at low temperatures. The invention proposes means that allow the required forward voltage to be decreased automatically depending on a measurement of ambient temperature.

摘要： A device and a method for controlling the electrical power supply of a plurality of light sources, preferably of light-emitting diodes, or LEDs. The plurality of light sources is divided into at least two groups of light sources. The invention is noteworthy in that it allows the use of a multiphase step-up voltage converter for all the groups of light sources, whereas the measurements of the input currents for each of the phases of the converter give a reliable indication of the level of power required by one of the groups being powered.
