Hello , I have included my best efforts at a schematic, and related formulas for my problem as an attachment to this post. Please take a look at it if you have the time.
My requirements are to produce 2 volts, and 13 amps, for 30-40 Milliseconds.
My constraints are
* a very minimal physical presence in terms of weight, I have 3 ohm resistors I need the requirements passed through in parallel ( I think they need to be in parallel, to receive the requirements simultaneously, simultaneity is a constraint)
* the power source must be physically disconnected for at least 20 seconds before the requirements are delivered to the resistors.
My variables are
* Just about any power source financially accessible less than a car battery ( expense )
capacitor Farad value can vary
Additional resistors or small lightweight components can Vary, (lightweight in the grams magnitude)
wire gauge has to stay pretty small
I've tried to model the probem myself by thinking about the Time constant in the V(t) = V(o)e^-(t/RC) equation, but I find that the one ohm resistors force the time constant into the nearly instantaneous condition, whereas I need 30-40 MS.
I have been stumped by this problem for months, and have asked many people, I wouldbe very impressed to find a nice elegant solution, and EXTREMELY appreciative. If you would like to reach me directly my email is joexsmurf@gmail.com I will check the forums often for a response.
Thank you for your time.
