INVERTER WITH AT LEAST TWO DC INPUTS, PHOTOVOLTAIC SYSTEM COMPRISING SUCH AN INVERTER AND METHOD FOR CONTROLLING AN INVERTER

摘要

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.
