Abstract

E' descritto un convertitore cc/ca con un invertitore (10) accoppiato a un carico (13) tramite un trasformatore (11). Un generatore di segnali di comando, (25) provoca la commutazione dell'invertitore secondo un criterio prefissato e un anello di retroazione (15-25) è sensibile ad almeno una grandezza di stato (vc-ic) del circuito per agire sul generatore di segnali di comando (25) in modo da modificare le grandezze di stato (vc, ic) in senso tale da assicurare un andamento stabile prefissato della tensione alternata d'uscita (vc). Per impedire la saturazione del trasformatore (11) è previsto un dispositivo circuitale che comprende mezzi di correzione (30-32, 33-35) atti a rilevare nella tensione d'uscita (u) dell'invertitore (10) uno squilibrio che provochi la comparsa di una componente continua sul primario del trasformatore (11) e ad applicare al generatore di segnali di comando (25) un segnale di correzione per modificare i segnali di commutazione in senso tale da annullare lo squilibrio.
