(PVI-6000-OUTD-US-W Rev.2.0)
The block diagram shows an AURORA PVI-6000-OUTD with the two input DC-
DC converters; in the Wind version the 2 converters are always connected in
parallel.
Thanks to its high efficiency and excellent thermal design, the AURORA inverter
provides maximum power operation in a broad range of ambient temperatures.
The inverter is controlled by two independent DSPs (Digital Signal Processors)
and one central microprocessor.
This way, grid connection is controlled by two independent computers in full
compliance with electrical power supply and safety regulations.
The AURORA operating system continuously communicates with all functional
blocks and processes the data to ensure optimal performance, as well as the highest
possible efficiency under all wind speed and load conditions, always in full
compliance with the applicable directives, standards and regulations.
