Bedini Capacitive Discharge Chargers

... just placed my solar on the balcony but fog and whole day rain stopped me...

That's where I like to use inverted trigger SS SSG instead. It will start charging in low light, even on cloudy day. Less powerful but better than nothing at all.

totoalas I would use higher capacitance, such as 20000uF and close to the operating voltage of your source (panel) - 25 - 40V max.

@Minoly
Thanks, 3 t o 4 hours still great will try to test my SSG 6 coiler , just placed my solar on the balcony but fog and whole day rain stopped me... the mono crystalline can also pick up up to 14 vdc pulsing on the charge controller from 9 am till 4 pm in this condition

@BlackCHISEL97
thanks for the cap size info m hope this woll speed up the charging process...

HAS ANYONE TRIED TO PUT A N S SERVER HD DISC DRIVE NEODYNE MAGNET ROTOR 11 INCHES IN DIA ON TOP OF THE CRT FERRITE CORE 6 COILER ??/

THANKS MATE

Bedini with cap

Hi guys did you find this cap discharge truly better?
What type of uf/voltage found best?
This is the capacitor in the scheamtic cause it's not clear looks like another battery?
Thanks

Hi Patrick,

Can a 60 W 18V dc Solar panel directly be connected in parallel with a 3300 uf 450 v cap going to a 6 coiler Bedini and out wit another 3300 uf 450 v parallel to the charge battery of 60 AH ????????

Also , in your video 7Ah charging 500 Ah batteries , how long did it take to top off the voltage in the batteries ????

thanks,

Hi Totoalas,
I'm the last person you want to ask a conventional question, re solar to cap.

It's been a while, I thought I mentioned the time it took in the vid, if not, I think it was somewhere in the 3-4 hour range.
I hope your builds are coming along well,
Patrick

Thanks Patrick

Nice circuit. In the case of a Zener diode, one would reverse the polarity as compared to the rectifier in the schematic, correct?

The cap dumps as soon as the diode going from the anode to the gate of the SCR starts conducting. If you want it to dump at higher voltages just keep putting more diodes/zener's/LEDs in series with the A to G diode until you get the level you want.

Wouldn't using the recovery winding for charging up a standard 12V battery
charger circuit also be another valid way to utilize the energy being
produced by a N-Pole motor?

Dual Function Recovery Winding

The purpose of a north pole motor seems as though it would benefit
from a certain modification where the efficiency of generating thrust
on the wheel would be offset by the use of a dual input facilitated
by sensor switches coupled onto capacitors.

When a primary capacitor is thrown into charging the power coil, its
energy transfers into the recovery coil and dumps into another capacitor
in parallel with many others. During the off pulse, one or two of them
would be thrown back to the primary while the rest are left to continue
absorbing energy from the magnetic interaction.

Hi Boguslaw, Maybe Dave will confirm this or add to it, I use these cap dischargers a lot.

To make it drop at 24 volts you just add the trigger/threshold voltage of the SCR (from datasheet) to the forward voltage drop (measured) of the regular diode or LED then add the required Zener to get to 12 volts so added to the 12 volts of the battery it will be 24 volts.

However the drop voltage will change slightly depending on the battery voltage.

The way the SCR is orientated in the negative line can be confusing.

Also I found that sometimes the SCR will not switch off and continues conducting (common problem), it should work quite well though with 10000uf and a joule thief.
I think it happens when the capacitor is too small or the source charging it is charging it to quickly to allow turn off. Or the capacitor takes too long to discharge.

I think this can be solved by using a triac in place of the SCR, the triac should turn off each dump, I think.

SCR's are fairly tough.

Here this should help you. Focus on the scr/cap/battery arrangement. It is a very versatile setup.

The cap dumps as soon as the diode going from the anode to the gate of the SCR starts conducting. If you want it to dump at higher voltages just keep putting more diodes/zener's/LEDs in series with the A to G diode until you get the level you want.



Dave

Very nice circuit ! Could you explain how to choose diode to obtain required voltage trigger ? For example I want it to protect my solar charging device. I plan big joule thief connected to small solar panel charging 10000uF 25V capacitor. I'd like capacitor to discharge into 12V small lead acid battery (7Ah) every time it reaches 24V.How to get it ?

non 555 cap pulsers

Can someone post a cap pulser that doesn't use a 555 or h11d1. I'm not good with ic-s and want to do it old style. Any links, sites, or post would be great.

Thanks
