Abstract

Η επινόηση αναφέρεται σε κύκλωμα ελέγχου της γωνίας έναυσης θυρίστορ σε μονοφασικές,τριφασικές ή πολυφασικές ανορθωτικές γέφυρες, καθώς και για τον έλεγχο της γωνίας έναυσης τράϊακ (Triac). Χρησιμοποιεί οπτοσυζεύκτες Ο1,Ο'1 σαν διακόπτες αντί μετασχηματιστών για τον συγχρονισμό της ημιτονοειδούς τάσης της γραμμής παροχής δικτύου με την γωνία έναυσης των θυρίστορ ή τράϊακ,απλοποιώντας σημαντικά τοκύκλωμα ελέγχου και ελαχιστοποιώντας το κόστος κατασκευής.Οι οπτοσυζεύκτες μπορεί να είναι opto-transistors,opto-triacs ή opto-thyristors.Βασικό χαρακτηριστικό του κυκλώματος είναι η απομόνωση που παρέχει στο ηλεκτρονικό κύκλωμα ελέγχου μεταξύ των τάσεων δικτύου και της τάσης ανόρθωσης.
