Abstract

Metodo di alimentazione di motori elettrici in cui per ogni semiperiodo di ciascuna fase di alimentazione, applica un impulso rettangolare di ampiezza e durata variabile combinando il valore di cresta della tensione con la durata dell'impulso in modo di ottenere una relazione fra tensione di uscita e frequenza generata senza produrre il "sibilo" proprio dei motori elettrici a induzione controllati in velocità mediante variazione di frequenza.
