ABSTRACT:
A cost-effective device for influencing the transmission of electrical energy of an alternating voltage line with a plurality of phases has phase modules, which each have an alternating voltage terminal for connecting to a phase of the alternating voltage line and two connecting terminals. A phase module branch extends between each connecting terminal and each alternating voltage terminal. The phase module branch is formed of a series connection of sub-modules, each having a power semiconductor circuit and an energy accumulator connected in parallel to the power semiconductor circuit. The connecting terminals are connected to one another. The power semiconductor circuit is equipped with power semiconductors that can be switched off and are connected to each other in a half bridge.
