Here is the same circuit I am looking at showing you one possible
connection path for the relay. As you adjust the pot (Variable resistor)
you can set the maximum voltage ceiling for the out going.
In this case a 50v SCR is used for controlling 12vdc.
If you were controlling two 12vdc batteries in series equaling 24vdc
the scr rating might need to be a 100 volt device and so on.
In this drawing the relay stops the incoming power from reaching the
other side. However in the case of an oscillator we can not do it that way.
We must stop the oscillator itself.
Last night I tested the max voltage my SSSG circuit could produce
using a 400v cap rated at 1500uF and all I had to do to light the neon
was tap the connection to turn it on.
Instantly a voltage of 70 volts plus is reached with a single tap.
One second of uncontrolled circuit operation is long enough to put
my oscillator in the dump. In 3 seconds I stopped at over 200 volts.
At 200vdc the voltage increase drops back or slows dramatically
due to the device parameters (MJL4281A)
So in doing this test I am learning.
