1. A power electronics system for charging at least one electrically operated vehicle, the power electronics system comprising:
- at least two modules, each module having at least one terminal pair with DC output, at least one rectifier, at least one AC input, at least one DC link, and switching elements having switching states, the switching elements arranged between the DC outputs of the at least two modules such that, between the at least two modules, at least one series and one parallel circuit configuration is selectively dynamically set by the switching states of the switching elements,wherein;
the switching elements include an inner switching element connected between a respective terminal pair of the at least two modules;
for each module, the switching elements include a respective pair of outer switching elements connected to the respective terminal pair of each module,when the inner switching element and the respective pair of outer switching elements are closed, the at least two modules are connected in the series circuit configuration, andwhen all of the outer switching elements are closed and the inner switching element is open, the at least two modules are connected in the parallel circuit configuration.

Abstract
A power electronics system for charging at least one electrically operated vehicle, wherein the power electronics system has at least two modules each having at least one terminal pair with DC output, at least one rectifier, at least one AC input, at least one DC link and a number of switching elements the switching elements are arranged at and/or between the DC outputs of the at least two modules in such a way that, between the at least two modules, at least one series and one parallel circuit configuration can be selectively dynamically set by suitable switching states of the switching elements.
