Abstract (en)
[origin: WO2008125493A1] In order to provide a cost-effective device (1) for influencing the transmission of electric energy of an alternating voltage line (2) having a plurality of phases with phase modules (5a, 5b, 5c), which each have an alternating voltage terminal (6a, 6b, 6c) for connecting to a phase of the alternating voltage line (2) and two connecting terminals (7p, 7n), wherein between each connecting terminal (7p, 7n) and each alternating voltage terminal (6a, 6b, 6c) a phase module branch (8ap, 8bp, 8cp, 8an, 8bn, 8cn) extends, which is made of a series connection of sub-modules (9), each having a power semiconductor circuit and an energy accumulator (15) connected in parallel to the power semiconductor circuit, and wherein the connecting terminals (7p, 7n) are connected to one another, it is proposed to equip the power semiconductor circuit with power semiconductors (13) that can be switched off and are connected to each other in a half bridge.
