A light dimmer, a 1 µf capacitor and a 12 V car ignition coil form
the simple line powered HV generator. The current in the dimmer is
shown in Fig. B. At times tp t2, set by the dimmer switch, the inner
triac of the dimmer switches on, and a very high and very fast current
pulse charges the capacitor through the primary of the induction coil.
Then at a rate of 120 times per second for a 60 Hz line, a very high
voltage pulse appears at the secondary of the coil. To obtain an HV dc output, use a voltage doubler. Dl and D2 are
selenium rectifiers (TV 18 Siemens or ITT) used for the supply of
television sets. High value output shock protection resistors, R, are
recommended when suitable.
