Abstract
The device is for feeding electricity into a power grid () with a DC generator (), a DC converter () and an inverter (), and particularly to a DC converter () suited for the device. The DC converter () comprises a choking coil () having two windings (w, w) that are magnetically coupled and conductively connected to each other, two switches (S, S) and three diodes (D, D, D), and is configured such that grounding of the direct current generator () at the negative output () thereof is possible and the power load of the switches (S, S) is kept small.
