Abstract
Described is a circuit for converting electric power between a three-phase grid and a single-phase grid. The circuit includes, in at least one embodiment, a first transformer that is connected to the three-phase grid, a number of first converter stages assigned to the first transformer, the associated DC intermediate circuits and the associated second converter stages. The second converter stages are connected to each other at the alternating-current side outputs with the aid of a series connection.
