A versatile rapid pulsing multiple pulse ignition controller (17) used in conjunction with an converter power supply (13) with a voltage sensor/controller (16) and with an ignition coil (3) and energy capacitor (4) comprising an ignition system providing rapid firing multiple ignition sparks at high converter power supply efficiency; which ignition system is suitable for installation on existing automobile engines and other internal combustion engines including diesel engines. The ignition is powered by an converter (13) working as a gated oscillator driving a power amplifier which is turned off by voltage level sensor/controller (16) when the converter output (14a) reaches a preset value or ground potential, as when an ignition pulse is occurring, giving converter (13) the highest possible efficiency and minimum power dissipation. Controlled ignition firing and multiple pulsing is provided by a multiple pulse controller (17) connected to breaker points or other electronic trigger (18). The ignition controller (17) includes a universal input trigger converter (19) for detecting and shaping the input trigger and providing the initial timing trigger for the spark pulse, a gate pulse width control (20) for providing the pulse train width and varying it with RPM, and a gated clock oscillator (21) for providing the pulse rate. When multiple pulse controller (17) is used in conjunction with power converter (13), voltage sensor (16), and an ignition coil (3) and capacitor (4), a practical, easily installed, low cost, ultra-high efficiency "rapid pulsing" ignition system is provided, capable of producing ignition of lean mixtures for substantially reduced exhaust emissions and increased engine efficiency.read more
