new and learning about electronics:
application: have a micro generator capable of producing from 0 - 10 VAC
problem: trying to harvest energy to trickle charge 4 AAA NiCad batteries
Have run the Ac through a Schottky diode bridge, then into a 4 farad ultracap, then onto a 8 VDC boost chip, into the Nicad pack.
Need to develop a circuit that compares the charge on the ultracap, to the output of the generator, when equal, connect to the boost regulator, as well as the Nicad pack. When voltage drops to 1.0 VDC dissconnect the regulator, and the Nicad pack. Lastly go back to compare mode and wait for the ultracap to recharge back to the input voltage. Dual N-mosfets ?
Any help, or direction is greatly appreciated
