  • Patent number: 8461714
    Abstract: A direct converter includes n input phase connections and p output phase connections, where n?2 and p?2. The direct converter also includes (n·p) two-pole switching cells for switching at least one positive voltage and at least one negative voltage between the poles. Each output phase connection is connected in series with each input phase connection, respectively, via a switching cell. To enable any desired and continuous current flow setting from an input phase connection to an output phase connection of the direct converter and, moreover, to exchange electrical energy between the two-pole switching cells of the direct converter, at least one inductance is connected into each series connection. A system including a direct converter is also provided.
