[RE-wrenches] Programmable Battery Charger

[jay peltz]

HI Jerry,

Just a standard bridge rectifier, with correct amp rating.
 AC to diode to CC, thats it.

All regulation is via CC.

> Very interesting, what diodes did you use to rectify the AC, it sounds similar to the wind machine designs I have worked with. Do you use a coil to regulate the AC amps to the diodes, it seams like you would need a "throttle control" the current someway besides the diodes them selves or the CC.
