Abstract

See full text

The disclosure relates to an inverter for supplying a power provided as a DC voltage at a DC input to an AC mains connectable to an AC output. In this case, the inverter includes a switching network with a plurality of semiconductor switches and a digital control unit for producing a digital switching pattern for digitally operated semiconductor switches of the switching network that are able to be used to produce a first output voltage (Uout,dig). The inverter additionally includes a linear control unit for producing signals for actuating at least one semiconductor switch of the switching network in a linear mode, wherein the linear control unit is set up to produce a voltage drop (Uout,lin) across and/or a current (Iout,lin) through the at least one linearly operated semiconductor switch to a target value that is dependent on an instantaneous difference between the first output voltage (Uout,dig) and a voltage (UAC) of the AC mains. The disclosure additionally relates to a control method for such an inverter and a photovoltaic (PV) installation having such an inverter.
