METHOD OF ACTUATION FOR AN INVERTER, AND INVERTER, PARTICULARLY SOLAR CELL INVERTER

摘要

The invention describes a method of actuation for an inverter arrangement with a feedback capability, particularly a solar cell inverter of a photovoltaic installation, having a direct-current controller (12) for producing a pulsating DC 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 pulsating DC voltage (u'). In this case, the direct-current controller (12) and the bridge circuit (13) are actuated in alternation with a continuous signal or a pulse-width modulated signal as a function of the magnitude of the desired pulsating DC voltage (u'), wherein two ranges of the output-side voltage (u') are defined.
