摘要： An inverter includes a DC/AC converter, a DC intermediate circuit on the direct current input side of the DC/AC converter, multiple DC/DC converters connected in parallel to one another on the output side to the DC intermediate circuit, multiple inputs each coupled to one of the DC/DC converters, and an EMC filter connected between the inputs and the DC/DC converters. The EMC filter includes chokes in all current-carrying lines between the inputs and the DC/DC converters and filter capacitors between the inputs and the DC/DC converters leading from all the current-carrying lines to ground. The chokes in all current-carrying lines from the at least two inputs are formed by means of choke windings on a common core of a current-compensated choke.

摘要： A photovoltaic system having an inverter and a photovoltaic generator connected to an inverter input is configured to track an operating voltage of maximum power from the photovoltaic generator. The system also includes an energy store coupled in parallel with the photovoltaic generator, to the input of the inverter. A temporal profile of the power output by the photovoltaic generator is recorded by the converter and compensates for fluctuations in power from the photovoltaic generator in comparison with a target power by adapting the power (PDC) output by it at the input or branched off from there in such a manner that the sum of the power (PDC) from the converter and the power (PPV) from the photovoltaic generator is equal to the target power (PSoll). The converter is operated in a tracking mode that it makes it possible to track the operating voltage of maximum power by means of the inverter. There is a repeated change between the compensation mode and the tracking mode during ongoing operation of the photovoltaic system in which power from the photovoltaic generator is available.

摘要： In order to operate a photovoltaic system including an inverter and a photovoltaic generator connected to an inverter input, the inverter predefining an operating voltage of the photovoltaic generator at the input and being configured to track an operating voltage of maximum power from the photovoltaic generator. The system also includes an energy store for electrical energy and a bidirectional converter, via which the energy store is connected, in parallel with the photovoltaic generator, to the input of the inverter. A temporal profile of the power output by the photovoltaic generator is recorded by the converter. The converter is operated in a compensation mode that compensates for fluctuations in power from the photovoltaic generator in comparison with a target power flowing into the inverter via the input by adapting the power (PDC) output by it at the input or branched off from there in such a manner that the sum of the power (PDC) from the converter and the power (PPV) from the photovoltaic generator is equal to the target power (PSoll). The converter is operated in a tracking mode that it makes it possible to track the operating voltage of maximum power by means of the inverter. There is a repeated change between the compensation mode and the tracking mode during ongoing operation of the photovoltaic system in which power from the photovoltaic generator is available.
