Abstract
A voltage conversion circuit for the conversion of an input d.c. voltage into a three-phase a.c. voltage (U, U, U) in the mains frequency range having at least one inductor (L, L) and having multiple switches (S, . . . , S) controlled by a drive circuit (AST) in which a first converter section is provided (S, D, L, S) to produce positive output voltage portions and a second converter section (S, L) is provided to produce negative output voltage portions and the output of the first converter section is connected to the three phase outputs (R, S, T) via one each of first longitudinal phase circuit breakers (S, S, S) and the output of the second converter section via one each of second longitudinal phase circuit breakers (S, S, S).
