Abstract
An ignition system for automobile industry is disclosed. The system includes a high voltage source to initiate the spark and a low voltage source to add additional energy to the spark and the initiation of the spark and adding of the additional energy to the spark is carried out while the primary winding of the transformer is conducting. This high energy ignition system is carried out using the transformer with a secondary high voltage winding. The spark generation and adding additional energy is carried out using both capacitive and inductive transfer system using the transformer. Different ways of generating high voltage are also disclosed. Both single switch method and two switch method and multiple switch methods are also disclosed. Current controlled spark generation and multiple pulse method are also disclosed. The system delivers more energy efficiently while the primary is on and with smaller transformer and faster current rise.
