System and method for providing multicharge ignition
James Alva Boyer,Norman H. Bracken,Raymond O. Butler +2 more
- 21 May 1999
TL;DR: In this article, a system and method of providing multicharge ignition are provided, which comprises the steps of charging an inductive energy storage device by flowing electrical current through a primary side of the inductive storage device until a predetermined amount of energy is stored therein, discharging a portion of the predetermined amounts of energy through a secondary side, and repetitively closing and reopening the path to recharge and partially discharge, respectively.
