Ok. I will look forward for your result.

If you can, I would be very interested to know the efficiency comparison of your JT with and without FWBR.

Joule Thief with bridge rectifier - Unexpected results

Hi Sucahyo sorry for too much questions and rough sketch but really want to do the best charger for my batteries. I'm posting circuits to be sure how FWBR should be used. Better AC caps as used on stingo then Electrolyte to BR?
Thanks for your response.

The bridge rectifier across the output of T1 is mostly wasted, as I explain in my blog here. Also the cap across the bridge rectifier's output is not needed and should be left out.

Yes I will inform you.

It would be more helpfull if you post some number of input and output measurement.


Notice that I connect the load negative to source positive, unlike yours. This change result.

When using FWBR with negative to positive, the FWBR will also capture the second spike. I believe switched coil produce bouncing wave, the FWBR capture the bouncing.

Original schematic was at http://www.energeticforum.com/renewa...harger-13.html

Connecting the bridge rectifier to the primary of T1 has some unexpected results. Fig.1 is the original schematic as seen at the link I gave. Fig.2 is the same schematic redrawn to separate the diodes of the bridge rectifier so one can see how they are actually connected. You can trace them down if you like and verify that there are connected the same as the original schematic.

It is very different.

When the coil collapse, mine current would flow from transistor to diode to battery to diode to cap to source positive. Yours would flow from transistor to diode to battery and cap to source negative.

When the coil collapse bounce back, mine current would flow from source positive to cap to diode to battery to diode to transistor, from coil going back to coil. Yours do not allow that.



I suggest cap isolated FWBR because I have twice more efficient result. Example:
YouTube - radiant recovery circuit, direct vs correa's converter

I can build joulethief right away and show video if you still have doubt. But please excuse poor attempt switching meter because I only have one.

If you prefer to your own experiment, please do try it your self. But please use the correct circuit.


I don't use negative to negative recovery because I don't want the battery getting charged even when the oscillation is dead. To get good efficiency at low frequency.


FWBR without capacitor produce twice output but at the cost of twice consumption. FWBR with capacitor in series produce less than twice output but have twice more efficiency.

With stingo, I would use the cap to block only the normal current.

BTW, I suggest at least 2 Amp diode for the FWBR. 1N4007 is only rated 100mA and stingo can produce more than 1 amp even with single diode. You will kill either the diode or the transistor with 1N4007.

Yes I will inform you.

Thanks .

Sucahyo, my friend, i took my ksc 5027, and i even found in one
new store tip 32, and i tested stingo and bingo with them, and
guess what ?...Much lower efficiency !...There is no reason not
to tell you the truth, i was very surprised, but somehow since
this transistors are at the first sight weaker i would be more
surprised if there was better result with them than with 3055/2955...
But, i tried, i can not say i did not try at least...
Never mind, i use to be surprised in electronics stuffs,
only i wonder how you get so good results with ksc 5027 ?

Rgds !

Watson, why don't you try it for real?

Watson's eBlog: November 2010

I came across this schematic through one of the Google Alerts that I received. Actually it was this schematic, but this is just three of the first schematic combined. I started to examine the first schematic, and immediately spotted the 1uF/250V capacitor in series with the diode. BTW, there is no info on what kind of diodes are used. But assuming this diode has no leakage, then when the power is first applied, the capacitor will charge up to the peak voltage, and from that time on, no further current will flow through this capacitor. And if no current flows, then for all practical purposes the capacitor is no longer providing anything to the circuit and could be disconnected with no effect on the circuit. The designer has added parts to the circuit without adding any useful purpose - they are just a waste.

Nope, the cap reduce consumption.

Moving on to the rest of the circuit, I noticed the TIP32C (from now on I will abbreviate these transistors 32 and 31) has its collector connected to the positive and its emitter connected to the 31's base. But 32 is a PNP transistor not an NPN. Therefore the current is flowing backwards through this transistor, and it should not be working as a transistor. It might act like a diode but transistor action would be almost nothing.

Read this thread from page one. Consumption is twice worse with PNP connecting in a normal way. cikljamas replicate and confirm it.

Harvey and Seamonkey mention that as PNP in inverted mode. Some people use it.

The above two gross errors are enough to make the circuit not function correctly. But then there are all those diodes connected to various points which complicate things greatly. I haven't concentrated on any of these, but at first glance some look like they would not be needed.

There are people replicating the circuit exactly like drawn and it work. There are some misunderstanding but the circuit is correct.

Moving back to the present circuit, my point is that the nonfunctional capacitor and diode seem to be an appendage that has been added to confuse the experimenter and obfuscate any attempts to duplicate the design. Or else if I'm reading too much evil intent into this, then instead perhaps the designer does not really know what he is designing and just throws in some parts to see what will happen. And when nothing much happens, just leaves them in the final design, while he's oblivious to what function, if any, the parts might have in the design. In other words, this "Rube Goldberg" has come up with something that through strange, devious, and round about way actually works. But I think that this should be more than obvious because with the present circuit, which was expressly designed to obtain "Free Energy" and in so doing violate the laws of physics, it points directly to the designer's mental point of view. This being that he is going to do something that no one else has done, and come up with the Perpetual Motion Machine.

No such intention. What I post is what I use. The design is inpired by Paulo Correa patents and scope shot at induction heater that show spike produce bouncing wave.

Seeing that 7imix produce sine wave too, using FWBR will capture that.

I am open to suggestion and everyone free to verify it. I prefer if you give comment after replicating.

I never promise free energy with this circuit. What I promise is a radiant circuit with high efficiency and give good result as charger or as spark maker.

Thanks for letting me know this. I am confuse too. My best is always from Fairchild KSC5027. I have greatest output with KSC5027. I hope this do not happen because I only use one meter to measure input and output.


Sorry that you have to waste money on that .

What is your best transistor combination then?

Dont worry, nothing bad happened, just ordinary electronic
surprise , we are going to see a lot of similar
surprises in future, which means we can not learn how
to swim if we do not jump in to the water, and we can not
be dry and swim in the water in the same time, can we ?
So, thanks for care, but i did not waste my money, cause
i am gonna use them some day for something else

3055/2955

I see. Thanks for that. Good thing it still usefull for you.

3055/2955

I confuse again because that is my worst .....

I guess brand can make huge difference, not type .....

Your best is my worst, and vice versa

Could be the brand, who knows, looking the specs for all these
transistors can not help much i suppose, but if we talk about
impression than i must say 3055/2955 makes better impression
on me then 5027/32...

Concerning 555 timer for relay (bingo thread) do you have by
the chance some good diagram for that purpose-driving relay
while charging the batteries ?

Cheers !

I have this circuit for zapper, but I think I will modify it as relay driver. The resistor and capacitor value need to be changed though.



I will post the circuit after I test it.

JT with cap and FWBR

Hi Sucahyo today I measured input to circuit and it was giving 70ma input on a 7v solar panel and 4ma out 1000v+ cause it was above meter reading.The thing is I never measured output when it was without but it seem that in cloudy climate the JT is still working cause the neon is lighting bright. Maybe this effect input too.
Ok If you want more info tell me thanks.

Thank you.

Can you test it with load? neon bulb or battery? Both may give different result too.

Hi friends, maybe it is not strictly connected with this thread but
i want to show you two of my devices that i made yesterday and
today...

First one is battery saving brightly 5 leds torch which drains just
9 mAmps from 12 V battery, and second one is battery tester
that uses LM 3914 ..

If you like it tell me and i ll post you diagrams and explanation
for 5 leds torch since it is my project developed on the basis
of one converter...

So, this torch if you liked it could be nice present for Christmas...

Cheers !

[sucahyo]

That is nice . I think you can make a thread for it. Do it need special coil?


BTW, here is the exact circuit that I use to drive the relay:


However I got unconsistent timing, I don't know what cause it, the timing sped up or slow down it self.. I just ignore it and try to switch load and source of two 3V. Will see what happen after hours of run.
