What did you use for FWBR diode?

Even my stingo with 1 ohm coil would need a much bigger diode. 1N4007 will get very hot quickly with just 500mA input at 12V.

1N4007 simply is not adequate for you.

Even 6A diode seems not enough.

Sucahyo,

What diode would you recommend? and can I have a smaller diode for the bridge from base to emmiter and a bigger one for the collecter, charge + out?
Although I kep doing transistors. what is a better transistor than a tip 35c?
Am I looking for one that can handle volts? or Amps? or both? or speed of switching? What is a good transistor I have had the best result with tip 31c although if I tweak too much pop.
I have ordered these NPN Silicon Power Transistors H29BUTT11A TO-220
Anyone that has input is welcome.

Best regards,

G.

The maximum amount of current a battery can supply can exceed their amp hour rating, although this take toll on the battery.

At least you should try to use 10 amp diode first and see what happen.

Sorry that I am not following your circuit, but can you post your diagram? where exactly that you put the FWBR? If you use induction coil, then you should try to ustilize the primary coil. Use FWBR but put a capacitor in series with the diode for current flow from the source to the charged battery.


Transistor that can handle higher current is usually less efficient.

Currently I use 2SC2922 for high current charging. It has worse efficiency from my other circuit but can handle big current. It is at the same price range as TIP3055. Not an ideal transistor but at least it survive longer. Spec allow up to 180V.

Try to look for high frequency high power switching transistor.

transistor with high voltage rating survive better. high amp rating needed if you use high output power.

Need a fantastic source for good trigger coil wire and Litz wire?

http://www.ebay.com.au/sch/pacproducts8 ... 4340.l2562
LITZ WIRE 10/44 250 ft
From United States
AU $9.63
+AU $5.36 shipping

47 AWG (GAUGE) MAGNET WIRE 2500 FEET
From United States
AU $6.74
+AU $5.87 shipping

Very reasonable.
If anyone has anymore info for windings please post.
G.G.

I think the last time I bought wire it was 50Php/ounce or about $1.25us at the local electrical store. If you bought it in a big real of (I think 10kg but it was about 12" high and about 5" diameter) it was a little over half that price which was getting close to the copper price. I know it originated out of China.

Always compare the price to the copper price and buy by the kilo.

Typically each process or middle man adds 5% to the price in SE asia. In the UK and US expect each midleman to add 42% (30% gross profit)

MR B and Sucahyo,

& all,

Hi again forced to build another fan, dead battery on car and gave my radiant chargers away except for cpu fan style not enough to charge the car batt,

Question Can the emitter and collector wires have more winds than the power and + to pot wire on a hex filler or even a bifiller?
will this work? as don't we want the smaller wire wound more for the collection of radiant energy?
Or will this not work has anyone achieved a result?

Regards,

G.

To whom it may concern,

So I wired a 6"" fan with hex filler wound stator cw,ccw,cw,ccw. 48 turns of roughly 3x32 awg and 3x36 awg wire.
with 3 x butt11a transistors and 1w 470ohm resistors and 3x1k wire wound pots and had only 3 x 110 volts neon's 1 for each transistor.
This is what I found.

I had a bright purple flash I mean bright and the 18v lithium 3amp hour battery sparked as well. so I knocked the positive off.
Then I connected to the car battery and fired her up all good, squeaky sound and charging.
So I took the negative off the battery for a split second, mistake number 2.\
The bright purple flash was so bright, the neon on the far right transistor caught fire where it was soldered and melted completely off from both connection of the collector and emitter.
The neon had also been burnt out you can see the damage.
So I wired another neon and connected back to the charge battery and fired her up.
All good I am thinking I will need at least 440 volts of neon bulbs for each transistor If I am to take it off charge battery I will update when I have.
Best Regards,

G.G.

It sounds good. I never remove the charging battery when it is running, I had a battery explode on me with acid everywhere, not good

Mr brown, or other gurus,
I am in need of advice of how to wind a fan hex filler and I would like to know if I can wind the thinner wire more wraps than the run wire that would be thicker?
that is more winds for the thinner to get more or higher voltages and less for the run wire for more amps to drive a 10 inch fan.
Please advise of a good book and videos and any websites you would recommend.
also Does flat wire allow a quicker release of the collected energy without as much lenz effect?

Regards,

Gmang73
