    Trying to optimise my system for power draw and output!
    Trying to help in what limited way i can atm!

    I guess we'd need a LOT of building and rebuilding in order to figure out the correct values of everything. But then the funny thing is if you try to charge a different battery with that machine, it seems all your planning and work has gone out the window lol. I suppose the key is to figure out the relationships between all the components, and even "external" components like a battery have to be considered a part of the design, and once you know the relationships then maybe it's a relatively simple process to plan it all and aim for certain values.

    Thanks

      Yeah, it does seem that way
      I read that with the SSG circuit, if you get everything tuned just right, including matching the batteries, you can actually see some charging in both batteries at the same time. I have a pretty large learning curve to go yet :P

        I tune my circuit using a 650uF 850V dc capacitor connected straight to the output of the SSG. I watch the volts build up....I turn the pot until I get maximum volts in the cap for the minimum amount of switching current.

        Im using a high current intel CPU fan with separated pair windings. I have also used a second fan as a slave circuit. The interesting thing is, I lock the blade on the second slave fan and turn it clockwise/anticlockwise until the neons are ready to explode. So to be clear, one fan is spinning, the other is stationary.

        All power coils are triggered from the one trigger coil. So I have 3 power coils (2 in series per circuit) and 1 trigger coil (2 in series).
