Abstract (en)
[origin: WO03041248A2] The invention relates to a voltage converter for converting a direct current voltage (UE) to a three-phase alternating current voltage (UR, US, UT) in the line frequency range. Said voltage converter comprises at least one inductance (L1, L2) and a plurality of switches (S1, ..., S9) controlled by a control circuit (AST). The voltage converter is provided with a first converter element (S1, D1, L1, S2) that produces positive output voltage portions, and a second converter element (S3, L2) that produces negative output voltage portions. The output of the first converter element is linked with the three-phase current outputs (R, S, T) via one each of first longitudinal phase circuit breakers (S4, S5, S6), and the output of the second converter element via one each of second longitudinal phase circuit breakers (S7, S8, S9).
