2.2 Data Transmission and Check
In case multiple inverters are used, they can be monitored remotely by using an
advanced communication system based on the serial interface RS485 or on the
Power Line Modem (PLM) technology. For further information, refer to the
corresponding sections of this manual.
2.3 AURORA Technical Description
Figure 4 shows a block diagram of AURORA. The main blocks are the input Dc-
Dc converters (called boosters) and the output inverter. Both the Dc-Dc converters
and the output inverter work at high switching frequency to minimize size and
weight.
This model of AURORA is transformer-less, that means that there is no galvanic
isolation between input and output. This allows an increase the inverter efficiency.
AURORA is equipped with all the protection needed to operate safely and to
comply with existing safety regulations even without an isolation transformer.
