Abstract
The application describes operating an inverter having an AC connection, a DC connection and an inverter bridge therebetween. The operation includes operating the inverter in a first mode in which, at the AC connection, an AC grid is supplied with electrical power via the inverter, and the voltage of the AC grid is controlled via a regulation of the inverter. If an increase in a current at the AC connection exceeds a current limit value: changing to a second mode and operating the inverter, wherein a regulation is adapted such that, via a virtual impedance, it limits the current at the AC connection.
