Abstract

See full text

A converter includes a DC link and at least one phase module that is electrically connected to the DC link and has a phase conductor (Lu) emerging from said phase module. The DC link has a positive potential connection (+VDC), a negative potential connection (−VDC), and a neutral point connection (NP). A first energy store is connected between the positive potential connection (+VDC) and the neutral point connection (NP), and a second energy store is connected between the neutral point connection (NP) and the negative potential connection (−VDC). The phase conductor (Lu) is connected to the positive potential connection (+VDC) via a first diode and to the negative potential connection (−VDC) via a second diode. An energy supply charges the first energy store and the second energy store. The energy supply is connected firstly to the neutral point connection (NP) and secondly to the phase conductor (Lu) via a switch.
