Abstract
A high power high energy distributorless ignition system for multicylinder internal combustion engines using a single energy storage capacitor (4), a single leakage resonating inductor (20) with a switch SS partially or entirely across it, and one or more coils Ti with bi-directional switches Si and with single or double hith voltage outputs, the system defining a compact coil assembly powered by a resonant converter power supply (12), the ignition power delivery controlled by means of circuitry based on a robust gate (17), an oscillator (19), and steering circuitry (21).
