Abstract
An energy system is specified, which comprises a wind power turbine or water power turbine, which is connected to a generator, with the generator having at least two stator windings. In order to achieve a simple and robust design without a transformer, each stator winding has an associated rectifier unit, and each stator winding is connected to the AC voltage side of the associated rectifier unit. Furthermore, each rectifier unit has a respective associated energy storage circuit, and each rectifier unit is connected in parallel on the DC voltage side to the associated energy storage circuit, with the energy storage circuits being connected to one another in series.
