Abstract
A converter circuit is specified for voltage maintenance in an electrical AC supply network (1), with the electrical AC supply network (1) having an associated voltage source (UR; US; UT) for each phase (R; S; T) for supplying an electrical load (2), with the converter circuit having a respective inverter (3) for each phase (R; S; T), which inverter (3) is connected on the DC side via an energy-storage capacitor (4) to a supply device (5). On the AC side, each inverter (3) is connected in series between the associated voltage source (UR; US; UT) and the electrical load (2) in the respective phase (R; S; T), and in that, on the AC side, the supply device (5) is connected to at least two phases (R; S; T) between the associated voltage sources (UR; US; UT) and the respective inverters (3).
