摘要
The present invention describes an electrical converter system for power supply systems, comprising at least two identical individual modules connected consecutively, characterized in that each individual module have at least four internal switching elements, at least one energy storage element and at least four connectors, wherein the connectors are paired and serve as a first and a second terminal pair; the internal switching elements of each individual module are designed in such manner that they are able to selectively connect one or both connectors of each terminal pair to the energy storage element; the cascaded connection of at least two individual modules is made in such manner that the connectors in the second terminal pair of a preceding individual module are each connected to the connectors of the first terminal pair in the respective following individual module, and at least one terminal of the first terminal pair of the first individual module of the cascaded connection and at least one terminal of the second terminal pair of the last individual module of the cascaded connection serve as terminals for the cascaded connection; and wherein the switching elements of the respective individual modules in the cascaded connection of at least two individual modules connect their respective energy storage element to the terminals of the cascaded connection in such manner that a selective serial or parallel connection of the energy storage elements is made.
