Abstract

E' descritto un alimentatore di energia elettrica a commutazione o SMPS includente un circuito raddrizzatore primario collegato ad una sorgente di energia elettrica CA, un trasformatore collegato al circuito raddrizzatore primario, un circuito raddrizzatore secondario collegato al lato secondario di un trasformatore, una porzione di rilevazione di fluttuazione di tensione collegata all'uscita del circuito raddrizzatore secondario per rilevare la fluttuazione della tensione di uscita, un generatore di segnale di commutazione per generare segnali di commutazione in conformità con i segnali di uscita della porzione di rilevazione di fluttuazione di tensione, un transistor di commutazione inserito tra il trasformatore e massa per eseguire operazioni di commutazione in modo ripetuto conformemente ai segnali di commutazione, un circuito protettivo per rivelare lo stato della tensione di uscita e arrestare il funzionamento del generatore di segnale di commutazione in stato anormale, ed un circuito di potenza o alimentazione ausiliare per alimentare la potenza di funzionamento al generatore di segnale di commutazione ed al circuito protettivo.Il SMPS comprende inoltre un circuito di rivelazione di interruzione di potenza o energia CA per rivelare se la potenza CA è interrotta oppure no ed un circuito di scarica per scaricare la carica elettrica residua del circuito di potenza ausiliare conformemente all'uscita del circuito rivelatore.
