[0:02]This is an EV Gray SR circuit. The purpose of this circuit is to show that you can split the positives from two paths of rectifiers and going through a spark gap where the load is the transformer.
[0:23]The high voltage pulse circuit is now turned on, generates a 60 hertz pulse through the spark plug.
[0:30]A high voltage diode only allows the spark to flow one way. We split the positives introducing a lower voltage pulse through the transformer.
[0:43]We turn up the variac and the pulses start to discharge the capacitor.
[0:49]As we turn up the variac further, the capacitive discharges becomes sufficient to drive the output load.
[1:11]The high voltage spark is a switch basically when the spark ionizes, it creates an ion bridge and allows the lower potential capacitive discharge to flow through the transformer.
[1:28]We leverage this switch to provide us with 60 hertz timing for the capacitive discharges.
