Reverse Bias Diode Test

I set up a test to see if reverse biasing a diode with a higher voltage than applied in the forwards direction will turn the diode off.

I placed a MO diode in series with a 12V. light bulb. When I connected this to a car battery, nothing happened. The voltage across the diode measured at 7.2V. So I added another car battery, in series. This time, the bulb did light up. Then when I connected my mains powered ignition coil module across the diode, the light did not go out.

Reverse biasing a diode with a higher voltage does not turn the diode off, when it is still forwards biased with the lower voltage. Something else besides the Step Recovery Diode effect must be responsible for the Water Sparkplug effect, and my Puff Spark effect. Especially since I'm not using a diode in my discharge circuit. Also, it's been reported that the Sparkplug plasma effect will work with a spark gap, rather than a diode.

As I understand the Step Recovery Diode pulse effect, the HV polarity itself has to reverse, and there is no LV forwards bias present. Otherwise, the SRD will not turn off and will not produce a pulse.

If somebody did watch, I do believe this movie is very important and I would advise to watch it to the end http://www.energeticforum.com/renewa...html#post24894

I probably could, if I could open the DVD disc.

You can use Handbrake to rip the DVD disc to AVI:

isolate the power supply

OK gang, I need help getting to the next step. Aaron, you said you have had no trouble getting a spark into a reversed diode. I'm having a lot of trouble doing that.

If you use a DPDT relay, you can make sure the power supply is isolated from the ignition coil.

Put the cap on the common and in NC position, it charges from supply, when relay is triggered, common moves to NO, which dumps cap to ignition coil..that way, there is no chance for power supply to be dumped directly to primary.

I wonder if the power supply may have killed the coil or over powered the diode?
