Modular Power Electronics System for Charging an Electrically Operated Vehicle

Abstract

A power electronics system for charging at least one elec trically 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 .
