Abstract

The invention relates to a power inverter for supplying power from first and second direct current sources with a common reference potential (0) in an alternating current network, wherein said power converter is connected, on the output side thereof, to the conductor (L1Netz) and to the neutral conductor (NNetz) of the alternating current network, the first direct current source has a potential (1) positive with respect to the reference potential (0), the second direct current source has a potential (2) negative with respect to the reference potential (0) and the reference potential (0) is connected to the neutral conductor (NNetz), the power inverter comprises a first step-down controller by which the positive potential (1) is connected to the conductor (L1Netz) of the alternating current network and a second step-down controller by which the negative potential (2) is connected to the conductor (NNetz) of the alternating current network. The inventive device reduces the number of necessary components to a minimum, thereby minimising power dissipation and raises the efficiency.
