An electrical circuit for producing a three-phase AC current from a low-power generator (10 kW to 5 MW) and for feeding the current into a power grid has a forward mode where energy flows from the generator to the power grid or to an energy-storage device and a reverse mode where energy flows from the power grid or from the energy-storage device back to the generator. To support the forward mode, the circuit has a generator-adjacent circuit stage with diode rectifiers and booster circuits, an intermediate circuit stage with two capacitor groups arranged in series, and a grid-adjacent circuit stage with an inverter. To support the reverse mode, the circuit has diode rectifiers and booster circuits in the grid-adjacent circuit stage, the two capacitor groups of the intermediate circuit stage, and an inverter in the generator-adjacent circuit stage. |
