Abstract:
Supply device for supplying a preregulated voltage to a plurality of consumer electronic modules, based on a perturbed DC electrical voltage, exhibiting a wide voltage variation range, the supply device comprising:a primary supply module providing the electronic consumer modules with the preregulated voltage; and each electronic consumer module including voltage conversion means outputting electrical voltages adapted to needs of the module; wherein said primary supply module is linked by respective individual supply lines to each electronic consumer module and, said primary supply module comprises: clipping means for eliminating high voltage pulses; filtering means for eliminating high frequencies; preregulating means for limiting and clipping overvoltages; voltage step-up means for supplying a voltage when an input voltage drops below a predetermined level; and means for protection against short-circuits placed at a feed of each of the individual supply lines of the electronic consumer modules; each electronic consumer module not including each of clipping means, preregulating means, voltage step-up means, and means for protection against short-circuits.
