Boost Converter | Works from even 0.5V
Вставка
- Опубліковано 5 жов 2018
- Hello friends, today in this video i have made a step-up / boost converter. The inductor in this circuit doesn't have any feedback winding that is why another transistor have introduced. This circuit is very efficient. One used 1.5V battery will power a bunch of LEDs for several days until the battery voltage goes below 0.6V. You can make a night lamp or even a bright white led flasher with this circuit. The output voltage goes around 40V without load.
Components used in this circuit:-
1) Bc337 transistor(NPN)
2)Bc547 transistor(PNP)
3)0.022nf / 22pf capacitor (Sorry for my mistake in the circuit diagram)
4) 47k resistor
5)Inductor from old CFL circuit
6) Enameled copper wire for coil ( Got from 5W CFL circuit's transformer)
7)4148 zener diode
8)10uf 35v capacitor
Thanks for watching.
Please like👍👍👍 share and comment.

Any idea if an axial inductor could be used instead of a toroidal coil? Any idea how many micro-henries? (uH)
Wonderful, You have done a great job. I was looking for this type of cct.
Nice build of a little JOULE THIEF circuit. Thanks for the upload.
WAIT ! how much does it output? you first powerded a hv led and then a 3v led
Hey would it be possible to go from .52 to 3.3? If so could you offer me some pointers
ola boa noite o amigo pode mi dizer quantas hora e a duração da bateria nesse circuito?
nice booster.
wow nice
Input me 3.5 volt benge or output me 12 cahiye to kon6a bala partch used carna hoga
cool!!!
Ok very goood
Nice
Super tailent bro
GREAT CIRCUIT! This should work from a 1-cell Earth battery. Just pound two dissimilar metal rods, like copper and aluminum, into the ground, a couple inches (or ?) from each other. Hook it up to the input and you should be able to charge batteries or whatever.
I don't think that's possible. While this circuit boosts voltage, it does so at the cost of current. More current is traded for voltage, and an Earth battery system simply won't output enough power to be useful, unfortunately.
@@dylanm.3692 Like any other battery, an Earth battery's current output depends on the size of the electrodes. Larger pieces of metal would yield enough current.
@@y1hardtop Those electrodes would have to absolutely huge. Way larger than anyone could feasibly manage. The soil only outputs very tiny trace amounts of power.
nice

Nice boost converter
Nice vidio 👍👍👍
Thanks
I am looking at building this to boost my solar pannel 18v to 45v
What should i consider adding to have it running for a life-time non-stop?
Sorry, this circuit will works between
0.2V to 3v,
@@TechIdeasAG what's required to operate it at 18v input and 40v output?
Now I noticed it was at the end of the clip!
can i know the components for making 0.01 volt dc input to 2 volt dc output?
Hi .Can you help. Can you write link
Transistor BC 557 (in your video)or BC 547 (in your discription), which one is correct?
BC557 pnp
Thank you for offering us this electronic circuit, just one question the diode is a 1N4148? I ask it because in the video you say it's a Zener, and the 1N4148, it's a high-speed rectifier diode, not a zener.
Greetings.
Yes , it's a 1n4148 diode.
Thank you
Wouldn't a more Simpler Joule Thief Circuit have worked as well, but with Fewer Components? Like the 2N2222 or up to anywhere in the 6000 Series Transistor. 1K Resistor or one Adjustable Resistor. One Non-Magnetic Toroid with 30 Turns of 24g Copper Wire. ( Maybe a Low ESR Capacitor and a Diode also could be used. Right? Just asking. I hope you'll Answer my Question Mate.
Hii, could you please give me a ckt diagram of this please
Apm max kitna output hoga aur input me kitna de skte h
Can you please provide the circuit diagram for this boost converter?
The circuit diagram is present at the last of the video. In the circuit diagram the electrolytic capacitor 10uf at the output should be connected to the cathode of the switching diode or small signal diode 1N4148. Instead of using diode 1N4148 schottky diode 1N5819 should have been used which is perfect for this joule thief boost circuit. The efficiency of the circuit depends upon the parts used such as power transistor 2SD965 etc., Inductor and schottky diode.
Can someone help me with this same circuit, but the output has to be 12v max. Which parts do I need instead?
The input is about 0,5 to 0,6 volts
Connect a 12v zener diode to the output
Thanks man
Good work
But can i use( bc 547 ) instead of Bc337. ??
That should work fine.
i have a 1volts and 10mA battery, would you please to show me how to increase it become 6volts and 1ampere? is that possible for me?
Sorry, there is no circuit to do this job
The output power ( current out x V) should be close to the input power (V in X current in). Only the voltage could be boosted up .
Impossible
If you have 10mW in the entrance never could get 6W in the output
I tried this and it didnt work. I connected a 1.24V battery and the output was about 1V. I need some help! I followed the instructions step by step. I used 22pF ceramic disk capacitors since I saw in the comments that that is what should be used. Should i have used the 0.22uF ceramic disk capacitors as listed in the diagram?
Update: Make sure you check out the pinouts on the transistors
I did the same work but it didn't work. The voltage of 1.5 was reduced to 1V
Same here
Today i followed the circuit diagram and it worked 💪
PS : it worked when i removed the 10uf capacitor connected to the load
Can we boost 3v 75m amp to 5 v 1.5m amp
Any solution for current amplification

1.5v cicuit can run 3.7v? or not
Why not specify the wire gauge, diameter of core or type of core?
Boa observação!
Yes
cannot use with solar input.why explain me.
Can I use any NPN and PNP transistor?
if you have HFE> 200 I think it works, I made a circuit similar to an npn transistor with 260 HFE and a pnp of 280 and it worked!
Toroid size and coil wire size??
Any other alternative transistor name except BC 337????
Any npn power transistor will work
Hello ...
Is it the circuit diagram is correct in the end of the video...
Same doubt
this method did not work for me, can you tell me why? give me a clue!
It will work if you use 2SD965 NPN transistor pin configuration is ECB and it will also work for BC337 NPN transistor pin configuration is CBE. The shown video of BC337 is misleading it should be 2SD965.Because the pin configuration with ECB of NPN transistor is matching. The circuit diagram is present at the last of the video. In the circuit diagram the electrolytic capacitor 10uf at the output should be connected to the cathode of the switching diode or small signal diode 1N4148.

bc557-bc547 ?
Wath coil 470mh? please help me its not working 😭😭😭
A circuit diagram would be helpful.
The circuit diagram is present at the last of the video.
Its very nice. SP br

Please watch the diagram at the end of the video
👌😀
can i put more widing on the coil?
0.022nf or 22pf ? which one?
Same thing 1pf is 1000x smaller than 1nf.
Mantap mas buka juga punya saya ipan saputra
😮😮😮😮😶😶😶🤔👍👍👍👍👏👏👏
Is diode ko konsa diode kahte hai
The diode is 1N4148 called as switching diode or small signal diode.
I gues There is a fault At 1:43. It's about BC337's pin out. And why did not measure the output Voltage by the help of multimeter??
Why use two transistors?
Can you please give us circuit diagram
Video me hain
Yes bro thanks
can we recharge our phone battery with this boost converter?
It's not that powerful
Tech Ideas ok thank you for replying.will appreciate if you can make a video of how to charge a phone.
Diode konsi hai ??
Zener 4148
@@TechIdeasAG Diode 1N4148 is a switching diode or small signal diode not a zener diode. Why are misleading ?
[2)Bc547 transistor(PNP)] not BC547, it is BC557
but bc337 pinout is cbe not ecb as you specified in the Visio ..it didn't work for me !!!!
