摘要： A transmission device transmits energy between multiple electrical energy networks, each providing a multi-phase connection voltage at a network frequency for electrical energy supply. The transmission device contains multi-phase multi-stage rectifiers and a control device, which adjusts the transmission of energy into at least one energy-receiving energy network according to an input by controlling the multi-stage rectifiers. The multi-stage rectifiers are each connected to one of the energy networks and to one another via at least one multi-phase transformer. Electrical energy flows via the transformer at a predefined transmission frequency from at least one energy-emitting energy network into at least one energy-receiving energy network. The transmission frequency is, in particular, multiple times the network frequency.

摘要： A method operates a multilevel converter for power factor correction of a polyphase mains voltage. Each phase of the polyphase main has an associated phase module with a plurality of sub modules which are connected in series and each have an electrical energy store. Each sub module can be connected to the phase of the mains voltage or disconnected there from by an electronic switch. A circuit breaker is provided for disconnecting the converter from the mains voltage. The converter has a regulation system by which the voltages of the phase modules are balanced when the circuit breaker is open.

摘要： A non-linear load in the form of an arc furnace with an upstream furnace transformer is supplied with electric power from a power supply device with a plurality of converter units. The converter units have a plurality of main modules with inputs connected to a respective phase of a three-phase grid. The converter units have a common star point between the main modules and the primary side of the furnace transformer. Each main module has a series circuit with a coupling inductance and a plurality of submodules. The submodules have a bridge circuit with four self-commutated semiconductor switches and a bridge path with a storage capacitor between input and output. The semiconductor switches of the submodules can each be switched independently of the semiconductor switches of the other submodules of the same main module and of the other main modules.
