Anordnung zur Einspeisung elektrischer Energie in ein Energieversorgungsnetz

摘要

The arrangement (10) has two frequency converters (40-42) including separated rail voltage intermediate circuits (60), where each converter is indirectly or directly connected to potential-separated, secondary sided winding systems (30) of a generator (20). The converters are connected to a control device (80). The control device controls the converters with individual pulse width modulated control signals (ST1-ST3). The converters feed current into an energy supply network (100) by a voltage with a multi-level characteristic when controlled by the control device.
