SCR, AC fan full size and ebike bateries

[icap123]

Hi!, all my respect and thanks for all users here, especially to Imhotep of course!!! they are all Freedoms Warriors for me!!!

I am a newbie and I have built a Imhotep Bedini fan with cap and SCR. For charging aaa, aa and 9v bateries they charge very well , faster then the conventionally charger (after a few charging and discharging cicles of course). Anyway I don't understand what I obtain with the SCR, I just replicated from bedini scheme hahaha, so:

1) can anybody explain me the SCR benefit?, is the same if I remove it?

this is my circuit:

Somedays ago I bougth an ebike with three 12v 12ah bateries each one, so now the single imhotep Bedini fan is not enough... I was thinking in parallel output or in this Imhotep post which data one year ago aprox about an ac fan full size:

2)anyone know anything about this ac fan full size? (I have a few ones from waste)

any observation will be appreciated, Thanks in advance!

Hi . Please refer me to where you find this circuit

cant find that scr circuit
I realy do not under stand what that specific scr and diode does

nvisser, the scr as used in this schematic will allow for a brief storage of charge in the cap before completing the discharge into the battery. It would be worth placing a resistor on the anode side of the diode which is triggering the SCR.

I see it as a simple capacitive discharge system, which builds up above the level of the battery being charged until it triggers itself to connect, discharging the cap into the battery. On other Bedini systems, an electronic timer is used to better isolate and time the switching action.

icap123, I have already answered you my opinion of the AC fan on another forum, so I wont say anything more here.

I know what it is used for and I had a thread last week about such a circuit and actualy got one working. see:http://www.energeticforum.com/renewa...e-battery.html
I need to know how the above scr circuit works and at what voltage above battery voltage will it trigger.
It looks to me like it will trigger at 1.4v above battery voltage. The voltage drop over the doide (0.7v) + the voltage over gate cathode of scr.(0.7v)???
