CONTROL METHOD FOR AN INVERTER, AND INVERTER, PARTICULARLY FOR SOLAR CELLS

摘要

The invention describes methods of actuation for a DC-AC inverter arrangement with a feedback capability, particularly a solar cell inverter in a photovoltaic installation, having a direct-current controller (12) for producing half-cycles of an output-side voltage (u') and a bridge circuit (13) that is connected downstream of the direct-current controller (12) and forms a desired AC voltage (u2) from the output-side voltage (u') of the direct-current controller (12). In this case, at least two different methods of actuation are performed for the direct-current controller (12) and/or the bridge circuit (13) which are selected on the basis of the output-side voltage (u'), wherein two ranges of the output-side voltage (u') are defined in which different methods of actuation take place. The methods of actuation can be performed for different topologies of inverter arrangements.
