Fig.4 AURORA block diagram
The block diagram shows the model AURORA PVI-3600-OUTD-UK-F-W with
its two input Dc-Dc converters. The two Dc-Dc converters are controlled in
parallel by the Wind maximum power point tracker control.
Thanks to its high efficiency and large heat-sink, AURORA offers max. power
operation over a wide ambient temperature range.
The inverter is digitally controlled by means of two independent Digital Signal
Processors (DSP), and one microprocessor.
Two single-chip independent computers maintain control in full compliance with
the electric standards relating to systems power supply and safety.
The AURORA operating system performs inter-process communication checks to
ensure the entire unit operates properly.
