Claim Text:
1. A system for charging at least one energy storage cell in a controllable energy store which is used to control and supply electrical energy to an electrical machine having a defined number of phases, where the defined number is greater than or equal to one, wherein the controllable energy store has a number of parallel energy supply branches, wherein the number of parallel energy supply branches is equal to the defined number of phases, which the coupling units are configured as full bridges and, depending on control signals, bypass the respectively associated energy storage cells or connect the respectively associated energy storage cells into the respective energy supply branch, and the coupling units further configured to a star point of the electrical machine connected to each of the parallel energy supply branches and the reference rail connected to a secondary side of a charging transformer.
