Abstract

Η εφεύρεση αναφέρεται σε ηλεκτρονικό μετατροπέα ισχύος συνεχούς τάσης σε εναλλασσόμενη (direct current to alternating current, DC/AC) (44) τύπου ανύψωσης-υποβιβασμού τάσης, με πηγή ενέργειας συνεχούς ρεύματος (DC) μία φωτοβολταϊκή (Φ/Β) συστοιχία (3) και μία έξοδο εναλλασσόμενου ρεύματος (AC), του οποίου το ηλεκτρονικό κύκλωμα ισχύος (1) είναι αναδιατασσόμενο και διασυνδέεται με το ηλεκτρικό δίκτυο (2). Το ηλεκτρονικό κύκλωμα ισχύος (1) του ηλεκτρονικού μετατροπέα DC/AC (44) ελέγχεται αυτόματα από τη μονάδα ελέγχου (36) έτσι ώστε η δομή του και η διακοπτική του συχνότητα να αναδιατάσσονται σε πραγματικό χρόνο με σκοπό την βέλτιστη προσαρμογή τους στις συνεχώς μεταβαλλόμενες συνθήκες λειτουργίας που επιβάλλει η Φ/Β πηγή (3) προκειμένου να αυξηθεί ο βαθμός απόδοσης του κυκλώματος ισχύος (1) και συνεπώς η παραγωγή ενέργειας που διοχετεύεται στο ηλεκτρικό δίκτυο (2). Επίσης, η μονάδα ελέγχου (36) διαθέτει τη δυνατότητα εντοπισμού του σημείου μέγιστης παραγωγής ισχύος της Φ/Β συστοιχίας (3), καθώς και μεταβολής των κερδών των ελεγκτών ρεύματος του μετατροπέα DC/AC (44) σύμφωνα με υπολογισμούς βελτιστοποίησης που εκτελεί ο τοπικός υπολογιστής (43) με τον οποίο επικοινωνεί έτσι ώστε να ελαχιστοποιείται η ολική αρμονική παραμόρφωση του ρεύματος που διοχετεύεται στο ηλεκτρικό δίκτυο (2) υπό τις εκάστοτε συνθήκες τάσης και ρεύματος εισόδου και εξόδου του ηλεκτρονικού μετατροπέα DC/AC (44).
