Abstract: PROBLEM TO BE SOLVED: To provide a converter circuit for maintaining the voltage of an electrical AC supply network. SOLUTION: This converter circuit is specified for voltage maintenance in an electrical AC supply network (1). The electrical AC supply network (1) has an associated voltage source (UR, US, UT) for each phase (R, S, T) to supply energy to an electrical load (2). The converter circuit has an inverter (3) for each phase (R, S, T), which is connected to a supply device (5) on the DC side via an energy-storage capacitor (4). On the AC side, the respective inverters. (3) are connected in series between the associated voltage source (UR, US, UT) and the electrical load (2) in the phase (R, S, T). On the AC side, the supply device (5) is connected to at least the two phases (R, S, T) between the associated voltage sources (UR, US, UT) and the respective inverters (3).

Abstract: PROBLEM TO BE SOLVED: To identify a method for operating a charger for a voltage-holding device. SOLUTION: In this method for operating the charger (1) for the voltage- holding device (2), a rectifier (5) of the charger (1) which is connected with phase inputs (PA, PB, PC) via transformer (3) having electric AC voltage supply system is driven by a drive signal (5) formed of reference charge voltages (ULA,ref ,ULB,ref , ULC,ref ). Charge voltages (ULA, ULB, ULC) for corresponding phases (A, B, C) are generated in the respective phase inputs (PA, PB, PC), and a substantially constant DC voltage (UDC) is generated on a DC voltage side of the rectifier (5). The respective charge voltages (ULA, ULB, ULC) are generated in the corresponding phases (A, B, C) in such a manner that charge currents (ILA, ILB, ILC) are made to flow to be substantially in proportion to phase system voltages (ULA, ULB, ULC) of the corresponding phases (A, B, C) of the electric AC voltage supply system (3).
