Experimental study of a low-pressure hybrid RF discharge
A Rogowski coil connected into the circuit of the loaded plate in point C measured the current I cap in case of the pure capacitive discharge. RF voltages at the output of the matching box (points A and D) as well as between the discharge capacitor plates (points C and D) were measured using capacitive dividers.
Capacitor Discharge Ignition
R3 provides a leakage path to safely discharge the capacitor when power is removed. I Q3, R5, R6, and the 6.1 uf capacitor are a one shot circuit to generate short trigger pulses for the SCR. A conventional SCR trigger circuit with a coupling capacitor will not work due to the low voltage available when cranking the starter motor.

capacitance
When the triggering circuit receives the triggering signal, the triggering circuit stops the operation of the charging circuit, allowing the capacitor to discharge its output rapidly to the low inductance ignition coil. In a CD ignition, the ignition coil acts as a pulse transformer rather than an energy storage medium as it does in an inductive system. The voltage output to the …

How to build Capacitor Discharge Ignition Circuit (CDI)
The CDI ignition circuit produces a spark from an ignition coil by discharging a capacitor across the primary of the coil. A 2uF capacitor is charged to about 340 volts and the discharge is controlled by an SCR. A Schmitt trigger oscillator (74C14) and MOSFET (IRF510) are used to drive the low voltage side of a small (120/12 volt) power transformer and a voltage …
