Abstract

Il circuito di comando (1) ha il compito di alimentare al carico una corrente (Ii) presentante una zona ad ampiezza elevata con rapido fronte di salita ed una zona di ampiezza minore. Il circuito è collegato in ingresso (2, 3) ad una sorgente di alimentazione a bassa tensione, e comprende una pluralità di circuiti di attuatore (6), collegati in parallelo fra i morsetti di ingresso (2, 3) e includenti ciascuno un condensatore (Ci) ed un carico (Li). Ogni circuito di attuatore (6) comprende inoltre un primo interruttore controllato (Swi), interposto fra il rispettivo carico (Li) ed una linea di riferimento (5) per consentire alimentazione e l'accumulo di energia da parte del carico rispettivo. Un secondo interruttore controllato (SWR) è interposto fra la linea dei condensatori (12) e la linea dei carichi (4), per consentire una scarica rapida dei condensatori nel carico (Li) selezionato tramite il primo interruttore (Swi) e il ricircolo della corrente dello stesso carico o la carica dei condensatori (Ci) con la corrente di ricircolo del carico.Figura 1
