Claim Text:
1. An onboard power supply system for a motor vehicle, comprising: a voltage converter having a first connection and a second connection, a voltage source electrically coupled with the first connection of the voltage converter, the voltage source being operatively configured to provide a predefined source voltage, a base energy accumulator having a first connection electrically coupled with the second connection of the voltage converter, and a second connection electrically coupled with a reference potential, the base energy accumulator being operatively configured to provide a predefined base voltage, wherein an amount of the predefined source voltage of the voltage source is greater than the base voltage, at least one first selection circuit of at least one first electric consuming device, the at least one first electric consuming device being arranged electrically coupleable parallel to the voltage converter, wherein the at least one first electric consuming device is acted upon by a voltage resulting from a difference between the predefined source voltage of the voltage source and the base voltage, at least one second selection circuit of at least one second electric consuming device, the at least one second electric consuming device being arranged electrically coupleable parallel to the base energy accumulator.
