  • Inverter with at least two DC inputs, photovoltaic system comprising such an inverter and method for controlling an inverter
    Patent number: 10033190
    Abstract: The disclosure relates to an inverter with at least two DC inputs, which are coupled to a common DC link, which is connected to an inverter bridge. At least one of the DC inputs is coupled to an additional DC link. The disclosure also relates to a PV system comprising such an inverter and to a method for controlling such an inverter of a PV system, wherein a power flow from at least one of the DC inputs is directed into the common DC link and/or into the additional DC link on the basis of suitably coordinated control of the DC-DC converter and of an additional DC-DC converter allocated to the additional DC link.
