Βέλτιστος σχεδιασμός μικρο-αντιστροφέα τύπου flyback για τη σύνδεση φωτοβολταϊκού πλαισίου με το δίκτυο χαμηλής τάσης
Σε αντίθεση με τις συνήθεις μορφές παραγωγής ενέργειας, φωτοβολταϊκά (Φ/Β) συστήματα δύναται να εγκατασταθούν εντός κατοικημένων περιοχών (κτηριακά Φ/Β συστήματα), όπου βρίσκεται και το μεγαλύτερο ποσοστό της κατανάλωσης ηλεκτρικής ενέργειας. Για τη παροχή της ενέργειας των Φ/Β πλαισίων στο δίκτυο, …
