DEVICE FOR FEEDING ELECTRIC ENERGY INTO A POWER GRID AND DC CONVERTER FOR SUCH A DEVICE

摘要

The invention relates to a device for feeding electric energy into a power grid (8) with a DC generator (1), a DC converter (2) and an inverter (3), and particularly to a DC converter (2) suited for said device. The DC converter (2) comprises a choking coil (15) having two windings (W1, W2) that are magnetically coupled and conductively connected to each other, two switches (S5, S6), and three diodes (D6, D7, D8), and is configured such that grounding of the direct current generator (1) at the negative output (5) thereof is possible and the power load of the switches (S5, S6) is kept small.
