Abstract

The present invention describes an electrical converter system for power supplies, comprising at least two identical individual modules connected in series, characterized in that each individual module has at least four internal switching elements, at least one energy storage element and at least four connections, wherein in each case two of the connections act as a first and second terminal pair; the internal switching elements of each individual module are designed in such a way that they can connect either one or both connections of each terminal pair to the energy storage element; at least two individual modules are connected in series in such a way that in each case the connections of the second terminal pair of a preceding individual module are connected to the connections of the first terminal pair of the respectively following individual module, and at least one terminal of the first terminal pair of the first individual module in the series circuit and at least one terminal of the second terminal pair of the last individual module in the series circuit act as terminals of the series circuit; and wherein the switching elements of the respective individual modules in the series circuit of the at least two individual modules connect the respective energy storage elements thereof to the terminals of the series circuit in such a way that there is either a series circuit or a parallel circuit of the energy storage elements.
