Patent ID: 7969238

Claim:
A device for influencing an electrical energy transmission of an AC voltage line having a plurality of phases, comprising: a plurality of phase modules, each of said plurality of phase modules having an AC voltage terminal for connection to a respective phase of the AC voltage line, each of said plurality of phase modules having a first connecting terminal and a second connecting terminal; each of said plurality of phase modules including a first phase module branch extending between the AC voltage terminal and the first connecting terminal; each of said plurality of phase modules including a second phase module branch extending between the AC voltage terminal and the second connecting terminal; said first phase module branch including a series circuit formed by submodules each having a power semiconductor circuit and an energy storage device connected in parallel with said power semiconductor circuit; said second phase module branch including a series circuit formed by submodules each having a power semiconductor circuit and an energy storage device connected in parallel with said power semiconductor circuit of said second phase module branch; said first connecting terminals of said plurality of modules being connected together; said second connecting terminals of said plurality of modules being connected together; said power semiconductor circuit in said first phase module branch including power semiconductors interconnected with one another in a half-bridge; and said power semiconductor circuit in said second phase module branch including power semiconductors interconnected with one another in a half-bridge.
