Maybe a dumb question but are you sure your diagram shows the IR840 connected properly as it seems backwards, or is it because it is on a positive line that drain goes to the +12v and the coil goes to source.

@HD

Nice waves, really nice Hendershot. You got to have guts to build one of those. I am curious to know which documentation you used to make the build.

My current build is what I will call a 3,6,9 coil - 3 primaries, 6 secondaries and 9 (what I call) sub-secondaries. I'll post it when it is finished. My idea now is to work towards increasing amperage and not the voltage. Voltage is too easy.

to increase amparage .....

any one know how ?

the only way i could find was to use a larg cap

and discharge it to a transformer and step it down....

ist

im am able to fill caps at a verry low cost from a 9v battery

i mean big caps motor start caps....   250vac 80 uf

currently i can put 140 volts in that cap in seconds 

as near as i can tell i need to match the cap for the coil so that in 1 pulse it will fill it and also dump it   then throw more togather to add up to the larger output

use same source battery and a match rotating transformer to the coils ie 3 coils in a ring then a 3 tranny a 4 coil unit then 4 primaries on 1 collector

agin    not built yet ...  just ideas

I assume you are filling the caps from a small inverter or vibrator /buzzer setup and discharging them into the transformer primary, if not, you can do the same energy integration in the primary of the transformer. Integrate current into the primary from the 9V battery until the core is near saturated, then release and the secondary will ring like hell with all the energy you put into the primary. This is the flyback effect and is used in early ignition systems and TV sets.

If you charge the caps very high and dump them into the transformer primary, you will reach a point where the energy transferred will at some point be limited by the saturation effect of the transformer. EI core standard transformers limit quickly.

When this happens you will need either an air gap in the transformer core or use an open ended coil like an auto ignition coil.

Hold onto them reigns, cowpoke! There could be a lot of bucking goin' on.
Extreme cataclysmic event delivered to the primary function point!

Overview
The definition of a high-side load switch is that it is controlled by an external enable signal, and connects or disconnects a power source (battery or adaptor) to a given load. Compared to a low-side load switch, a high-side switch sources current to the load, while the low-side type connects or disconnects the load to ground, and therefore sinks current from the load.

The high-side load switch differs from a high-side power switch. The high-side power switch manages the output power and, therefore, typically limits its output current. Conversely, the high-side load switch passes the input voltage and current to the load and, as such, it does not incorporate the current-limiting function.

Is this a shot of the elusive "kicks" or just a transformer coming out of saturation? You decide.
