Booster caps.............
Hey Greg,
Thanks for that reply, I think I have a pretty good handle on the circuit now. The fact that it's switched using the negative instead of positive, works out even better for me. I plan to re-configure a distributor to trigger the circuit with a 12V negative signal.......PERFECT. As for the "backside boosters", you REALLY have not seen the "effect" at it's full potential until you hook up a booster cap on the back side. As I said, this is not my design. I can only wish I came up with it, and thank Aaron REPEATEDLY for sharing it. With your triac setup, you should be able to hook up an extra single triac to charge the booster cap, the discharge will take care of itself when the coil fires to the plug. You can trigger it to charge the booster cap the same time the front triac charges it's cap. Since your circuits are well isolated you should be fine using the same power supply to charge both caps instantaneously. I have had success with only one inverter using this setup. I did get some feedback and fried one inverter, but I did not know how to isolate the circuits at that time. You may want to try a separate power supply first, just till you can verify everything is cool. I'm still new with all this electronic stuff. The schematic you want to see is on page 8 of this thread, Aaron also uploaded a video of this a few posts below the schematic. You are going to LOVE this, trust me! I am now going to order a few triacs and caps and diodes, to further enhance my circuitry. You MUST try the booster cap setup, the effect is trully ASTOUNDING!!! Use the same high V microwave diodes for the "booster cap" as you have from the coil's HV+ to LV+. You hook up the HV diodes from the coil's HV+ to the "booster cap" positive, and then ground the "booster cap" negative to the base of the sparkplug. And VIOLA!! The results had me doing backflips in the shop! Happy testing, please post your results once you try the "booster cap", I would like to see how well it works with the triac setup. Thanks, have a great day............................Mike
