Abstract

L'invenzione prevede un dispositivo per la regolazione di carichi alimentati con corrente alternata, ad esempio per la regolazione della intensità luminosa di lampade ad incandescenza, del quale si fa uso di un transistor bipolare a gate isolato collegato in parallelo con un ponte raddrizzatore, transistor che viene innescato al passaggio per lo zero della tensione alternata di rete e viene disinnescato in un punto della semionda variabile in funzione della tensione da erogare al carico.Nel dispositivo secondo l'invenzione risulta mantenuta entro i limiti normativi l'emissione di radio disturbi, evitando così la necessità di ricorrere all'utilizzazione di filtri anti-disturbo.
