Abstract
A wind park for feeding power into a supply network at a connection point is provided. The wind park includes wind turbines for generating the power, a DC network for transmitting the power to the connection point, an inverter configured to transform electrical DC voltage into an AC voltage for feeding the power into the supply network, at least one DC-DC converter for feeding the power into the DC network. The DC-DC converter includes a switching device and a transformer with primary and secondary sides. The primary side is coupled to the at least one wind turbine via the switching device and the secondary side is coupled to the DC park network via at least one rectifier. The DC-DC converter is configured to apply a DC voltage of changing polarity to the primary side by the switching device to transform a DC voltage of the at least one wind turbine.
