Abstract
Disclosed herein is a multilevel converter () for voltage conversion between a three-phase AC voltage and a DC voltage, comprising three converter arms (), each having a first end () for connecting to a corresponding phase of a three-phase AC voltage source () and a second end (), wherein each converter arm () comprises a plurality of sequentially interconnected modules (), a main energy store () having a positive terminal () connected or connectable to a positive conduction line () and a negative terminal (), a switching arrangement (), a control system (), configured to establish a positive state, in which the negative conduction line () is connected with a star point () of said three-phase AC voltage source () and the positive conduction line () is connected with the second end () of one or two converter arms () to which a positive phase voltage is currently applied, and a negative state, in which the positive conduction line () is connected with said star point () of said three-phase AC voltage source, and the negative conduction line () is connected with the second end () of one or two converter arms () to which a negative phase voltage is currently applied.
