Abstract
Disclosed herein is a system () for providing N bipolar AC phase voltages U, with j=1 . . . N, said system () comprising N modular energy storage direct converter systems (MESDCS) () and a control system (), wherein the first ends () of each MESDCS () are connected to a common floating connection point (), and wherein the j-th MESDCS () is controllable to output at its second end () a star voltage Uwith respect to the floating connection point (), with j=1, . . . , N, wherein said system () is configured to provide each of said phase voltages Uas voltage differences between two of said star voltages, such that U=U−U, or U=U−U, for each j between 1 and N−1, and U=U−U, or U=U−U, respectively, wherein said control system () is configured to control each MESDCS () to output a corresponding unipolar star voltage Us, that can be decomposed into a periodic bipolar AC function P(t) and a unipolar offset U(t) that is common to each star voltage U, such that U(t)=P(t)+U(t), wherein the absolute value of said common unipolar offset U(t) is at all times t sufficiently high that U(t) is unipolar,
