| Abstract |
The development of a PV-converter based on the advanced Multi-String concept results in significantly reduced
specific costs while still profiting from the well-known advantages of the String-converter technology developed
by ISET and SMA in the mid-nineties. The paper deals with the basic considerations from a system’s point of
view that resulted in the development of the Multi-String-converter. The features of the Multi-String-Converter
concerning operational behaviour and PV-system design are described. Due to enhanced capacity of the
operational control unit the Multi-String-converter can be used additionally for active compensation of
harmonics and reactive power in order to improve the power quality. An evaluation of Multi-String-converters
in comparison with String-converters or conventional Central-converter concepts is presented. The selected
topology and the control strategy for the Multi-String-converter are introduced. |
