Abstract
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.
