Application overview
Following picture shows the typical architecture of a photovoltaic system for grid connected
application and composed by the photovoltaic field and the electronic part:
Figure 2.
Photovoltaic field is composed by PV panels. Some PV panels are connected in series to
make a PV string. Each string is connected in parallel to the others and then connected to
the electronic part of the system, the “inverter”, having the role of adapting the produced
power to the characteristics of the public electrical grid.
Other electronic components are the bypass diodes and the blocking diodes.
Each bypass diode protects the panel to which it’s applied providing an alternative path to
the current flow generated by other panels. These diodes guarantee both the panel
protection and the whole system functionality in case of damaged or shaded panels.
Blocking diodes (or “cut-off” diodes) protect the whole string from current reflow from other
strings due to a lower voltage on the string typically caused by shadow on a part of the
string.
Inverters are complex systems normally including 3 functions (DC-DC conversion, DC-AC
conversion and Anti-Islanding) managed by a main controller typically implemented by a
microcontroller or a DSP and executing following actions:
