Charging a low-voltage high-C capacitor. Efficiently


Posted on Feb 7, 2014

The first option is of course a zener. I actually have a bunch of 2. 2V which would protect the capacitor fine. The problem is, of course, half the energy is going to be wasted across the diode short. Is there any way I can regulate the voltage below 2. 3V without reducing the efficiency so significantly EDIT I`ve seen a few suggestions elsewhere that suggest putting a high-ohm resistor in series with the zener, presumably to minimize

current through it (therefore maximising it into the capacitor). How effective would this be
