Abstract
A power supply for a plurality of electronic modules in a compartment. DC electric current is provided to a plurality of consumer electronic modules on the basis of a perturbed DC voltage exhibiting a wide voltage variation range. The supply device includes a primary supply module and a voltage preregulator able to step up or step down the DC voltage in order to provide the modules with a preregulated voltage exhibiting a small voltage variation range. Each module includes a voltage conversion device for providing the voltages adapted to the needs of the module.
