Abstract
An inverter and method of controlling an inverter, which is connected between a photovoltaic generator and a power supply network for ride-through of a network fault, is disclosed. A voltage dip is detected in the network voltage and the voltage of a DC voltage link of the inverter is monitored. When the DC link voltage exceeds an upper limit value, an operating mode for ride-through of the network fault is started. The upper limit value corresponds to a saturation voltage in the specific I/Ucharacteristic curve of the inverter, above which the maximum AC output current of the inverter decreases. In the FRT operating mode, an energy dissipation device dissipates power from the DC voltage link and is controlled to keep the DC link voltage within a range below the saturation voltage.
