I am looking for some help in planning a NiMh battery zapper circuit. I have the fundamentals down but am looking for a little help to get the project tweaked and ironed out.
I would like to charge a 47,000uf cap to approx 80 or 90v DC and then discharge the cap through the battery. The batteries are approx 1.2v and 3300mAh rated with an internal resistance of approx .002 to .003 Ohms. The circuit should discharge the cap through the battery in less than a few milliseconds and should be able to withstand the current associated with the discharge.
The other problem would be the circuit to actually charge the cap since I want to be able to operate the unit off of 12v DC.
Any help would be greatly appreciated.
Thanks
