摘要： An apparatus for the generation of ignition power and its circuits is composed of two transformers and one discharging capacitor. The triggering signal is taken from the alternating current supply voltage. The stored charge is discharged through a primary winding of a step-up transformer. The secondary voltage is stepped up to several ten thousand peak volts which is enough to make an ignition spark through a large air gap. The first half wave of alternating current power charges the capacitor and the second half wave triggers an SCR to discharge the capacitor. The charging and discharging are completed during a single period of a line power wave.
