Claim Text:
1. An electrical converter system for power supplies, comprising a plurality of identical individual modules in a cascade connection, characterised in that each individual module has at least three, preferably at least four internal switching elements, at least one energy storage element and at least four connectors, wherein the connectors serve in pairs as a first and a second terminal pair; and at least two individual modules are cascade connected in such manner that each of the connectors of the second terminal pair of a preceding individual module is connected with wherein the switching elements of the respective individual modules in the cascade connection of the at least two individual modules connect their respective energy storage elements to the terminals of the cascade connection thereof in such manner that the energy storage elements of each individual module may be selectively connected to the energy storage element of a subsequent individual module either in parallel or in series, thereby allowing control of a consecutive connection of several individual modules in such a manner that at least one series connection of energy storage elements and at least one parallel connection of energy storage elements is present simultaneously in such consecutive connection, and wherein a diode is additionally arranged parallel to each switching element, the diodes being connected in such manner that they protect the switching elements from polarity reversal and overload.
