URGENT! WATER AS FUEL DISCOVERY FOR EVERYONE TO SHARE

Hi Greg,

Thanks for the explanation. So, the coil being inductive, when the triac is on, the coil's magnetic field is at its expanded state in one direction and the diode is not conducting. But when the triac turns off, the magnetic field collapses and induces a voltage across the coil in the opposite direction but faster if un-impeded. But because the polarity of the induced voltage now places the diode into its conducting mode impedes the speed of collapse and maybe prolongs this condition?

Also, I think that by being a CDI, at the moment the triac turns on, the high voltage at the secondary spikes very fast and very high, much faster than the one induced by the collapse.

Sorry if I am inquisitive. I just want to have a better understanding when I build one like it.

All,

My small power inverter is taking shape now. I have changed the oscillator frequency to approx. 1000 Hz.
I have added a input filter and also a output filter as shown in the drawing. The output filter is a voltage
depended resistor(VDR). This resistor will take "off" the highest spikes from the AC and regulate the
output to 355 Volt AC. The VDR will also double up as a protection if any "nasty" high voltage spikes
leak into the inverter. My load for testing is a 230VAC 25 Watt light bulb. The light bulb is glowing
ultra bright due to the higher voltage output. I estimate the load to be close to 27,7 Watt. The inverter
is using 2,89 Ampere at 11,1 Volt = 32 Watt. So the inverter itself is only "spending" 4,4 Watt as heat.
This is equal to 86,4% effectiveness. Not so bad for a simple inverter as this. The inverter uses 0,1 Ampere
at 13,6 Volt = 1,36 Watt when there is no load at the output. This is very low compared to the ready
bought inverters. I have not tried a maximum load on the inverter yet but estimate the inverter will
survive up to a 40 Watt load on the output. Next test will be a duration test with a smaller load.

[EDIT 1] Do NOT run the inverter without a load. The transistors will blow due to over voltage!
            (Found out the hard way! Has to change my transistors to better types.)

[EDIT 2] It seems that both transistors are OK. I think I blew the 4047 IC. Maybe I need some
             protection diodes on the transistor gate?

[EDIT 3] The 4047 IC can only source or sink 10mA at maximum so I changed the gate driver resistors to 1K.

Hello insane4evr,

I am glad you asked.  It's better to ask than assume these diodes are somehow part of the plasma effect.  If you don't use them then I guarantee you'll have a plasma effect of an undesirable kind ... and a lot of smelly smoke too.

Sincerely,

Greg

Thank you for posting the parts list. I now see I've missed a part and will order it. Again  Thanks very much Greg.
