Abstract: Exemplary embodiments are directed to a method and switching arrangement for an inverter. The inverter including a positive direct current pole, a negative direct current pole, and a neutral direct current pole. The arrangement having a first controllable switch connected between the neutral direct current pole of the inverter and a virtual neutral point of an alternating current network supplied by the inverter; and/or a second controllable switch connected between the neutral direct current pole of the inverter and an earth potential of an alternating current network supplied by the inverter.
