Abstract

A method for limiting an output power of an inverter having an output bridge and an upstream boost converter includes determining a first measurement variable representative of a bridge temperature and a second measurement variable representative of an output power of the inverter. The method also includes determining a third measurement variable representative of a generator voltage at generator connections of the inverter or a fourth measurement variable representative of an output voltage at a power output of the inverter, and reducing the output power supplied to a power supply grid to a reduced power value. The reduced power value is determined based on the first measurement variable, the second measurement variable and at least one of the third and fourth measurement variables. A control device having such functionality is also disclosed.
