Abstract
Un sistema elettronico di alimentazione per accensioni a scarica capacitiva per motori a combustione interna. Un circuito ausiliario di circolazione della corrente di carica del condensatore di accensione, in parallelo ad un avvolgimento statorico, privo di spire si cortocircuito del generatore elettrico del sistema di accensione: il circuito ausiliario comprende un interruttore elettronico controllato da un comparatore di tensione che è alimentato con una tensione di controllo di uno stato del comparatore, funzione della corrente del circuito ausiliario, rispettivamente alimentato con una tensione di mantenimento di detto stato del comparatore; queste tensioni vengono comparate con una tensione di riferimento di valore prefissato. Al variare della tensione del generatore, il comparatore di tensione causa un azionamento in rapida successione dell'interruttore del circuito ausiliario per convertire l'energia accumulata nell'avvolgimento statorico del generatore, in una tensione di carica del condensatore di accensione. Un dispositivo di inibizione interdice il funzionamento del comparatore di tensione al raggiungimento della tensione massima di carica del condensatore.
