Abstract
In an energy supply circuit for a motor vehicle on-board electrical system with two voltage supply branches at different voltage levels, the first voltage supply branch can be fed by way of an electric direct voltage converter by the second voltage supply branch and the second voltage supply branch can be fed by a generator. A multi-level controller W with three voltage levels is provided whose first in/output is connected with the second voltage supply branch, whose second in/output is connected with the first voltage supply branch and whose third in/output is connected with the energy accumulator B assigned to the first voltage supply branch.
