Miniature Voltage Booster. 3 to 500 V 

Finally someone who is speaking in a "tutorial". So sick of the music only videos.

This is an excellent circuit, it is nice and simple ! Thank you for giving the component value of the resistor, part number of the MOSFET, etc. Keep up the good work !

Thanks for your vids. Simple circuits, good explanation. I like them.

Keep the videos coming simple easy to understand and very useful !

Thanks for the video. Your explanations are always clear and easy to follow. Please continue more projects.

Thank you for giving the component value of the resistor, part number of the MOSFET

I like the new intro, good job

You are really an awesome teacher as well as an engineer. You are one of my inspirations. Thank you.

I am really impressed by your simplicity and creativity. Just Awesome!

That was a awesome video! This is perfect for a high voltage project from which I use a AA battery for a coil gun

One of the better videos on voltage booster, Thumbs up!

First technical video Ive seen that, within 2 minutes, I realized I had not questioned anything I had just watched! Your videos are very thorough and to the point, provide a quick study, and you are very pleasant to listen to. I subscribed within 2 minutes! Keep this up and you'll reach the entire network!

Nice and simple design for 3v to HV booster

Honestly, these videos are so good

Hey man, thanks for making these videos. They are very educational. I have been watching your them for a while now, and really you are what got me into hobby electronics. Also, your english is getting much better! (no offence)

I learn much from you. Thank you!

Very nice tip! Finding parts in waste light bulb. Very smart idea.

Highly educative. Thanks for this.

very informative to understand basic transformers and how they work, thank you. thumbs up

It's a nice circuit I've built this before with a BJT but I'd never tried it with a MOSFET. I'm really excited to build this.

Soooo concise, simple, clear! You are finally number one. Subscribed! Thumb up! I'm sure you can and will make a video on mini Voltage display with 7-segments display, WITHOUT programming or Arduino, using common integrated circuits. Thanks.

loved the vid excellent explanation, and you helped me with the power supply for my Geiger counter I am building Thanks

GREAT VIDEO! thank you sir so much for giving free information to the people!!

Thanks for the tut.. Awesome now have a circuit to run the heater in the 2C39A uWave valve i am going to use in a 1.2GHZ tx tripler I am building. My wife said the valve in its mount looks like the robot from "Lost in Space".. Good enough reason to build it... 500VDC, tick, the rest is down hill, thanks a bunch, great work..

Hey, very well explained. I've liked it very much, learned a lot! Thank you!

Brilliant as always brother.

A new intro! MUCH better than the old screeching sound :-)

Awesome explanation sir really ur work is educational

It boosts my interest on electronics

Very good explanation, thanks men.

Thank you for making a video about this with an actual explanation unlike so many others! Does transformer ratio determine step up as turns ratio or does it depend on mosfet on/off frequency? What component needs to be added to change that frequency?

Appreciate it. Easy and clear explanation. But I have to listen it carefully.

This circuit is known as a "Flyback Transformer" It works but without significant filtering the voltage on the output will have lots of spikes. You will need a RC and a LC filter possibly 2 of each to get the ripple down if you plan to use this circuit in music.

Thanks Ludic!

very good project.

all your videos are informative and super useful .. thank you so much

Awesome work

Simply awesome

I start open my eyes very very cool stuff thank alot

awesome thanks for sharing - great video.

100 working. Thanks for your help.

Really appreciate it guy

You changed my life sir! You will hear from me one day! Haha

It would be useful for us if you explained how you arrived at the conclusion that they coil & mosfet can only handle the limits that you described in the video. It would also be beneficial if you used the datasheet for the mosfet & showed your calculations. Thanks for sharing. Very nicely done vid!

Thank you so much

Wonderful explanation. God bless u

Great, I will try it.

muchisimas gracias lo voy a intentar hacer en mi casa para unos proyectos, sigue asi, gracias

Brilliant video, thanks. Would this give a similar shock that an insulation tester gives?

Best.detail and good

Super explanation

Thanks for your vids

Thanks you for good teaching 😊

instead of disassemble the fluorescent light, is there a part number available for the coil?

Obrigado. Bem expirado. Tanks very much.

disposable fuji flash camera works well for that, then add another ultra fast diode to charge two capacitors in series, doubling the output to around 800V

great job 👍👍 ,Thank you

Hello Sir This circuit produces spikes I have simulated it then how it produces AC as u said? thanks

thank you

How did you determine which is negative and positive output from the bottom coils? Where do you run the output from?

OK it's very nice

if i want to get AC, do i still need a resistor? does the resistor changes the frequency ?

Well i get it sir. If we install a thick coil in the secondary with 5 turns so will it give high ampere with a bit low voltage. Please reply. Thankyou

Hi Ludic I really enjoy your meticulous explanations. What country are you from ?

I am loving the positive comments here... :-) 1. Can i replace the 180 Ohm resistor with a varriable resistor or potential-meter so i can varry the output? 2. What can i improve on the circuit to be able to use it as a booster for my solar pannel outputting 17 volts.

Love You

thankyou for clear explain this video

Which cap and divide you use to multiple current 500 v to 1000 v ?

How many turns is on the secondary coil? I am thinking to use a toroid ferrite core to wind because I may not be able to get the exact transformer you have.

Great video! What would need to be adapted to be able to supply more than 2W? Say 100W?

nice tutorial thanx

Excellent!

Hi, you have very good channel so thank you for all your videos. Quick question: I made this kind of voltage booster using small pcb transformer. I simply wired new primary coil and used old mosfet. My resistor is 100ohm. For the output, I use "secondary" side of that pcb transformer and I have connected it to a rectifier and therefore I have full DC output. When I charge a capacitor, it goes up to 220VDC. My input power is from adjustable lab power with 4.00VDC and roughly 150mA. If I try to adjust it to higher voltage 5VDC, amps go up to 3-4A and it won't charge my load capacitor. Can you explain what is causing that? Why can't I use higher voltage for higher output? If I turn it down to 4VDC, amps go down and the output voltage is back to normal.

Really nice! :)

@Ludic Science can we use normal electrical tape to isolate the two winding of ferrite transformer?

An excellent adaptation of the blocking oscillator/ joule thief circuit! Appreciate the novel used of the CFL boost inductor to make a flyback! One query- in your initial test you don't have any load or bleeder resistor at the output. Where is the power being dissipated? Is the operation different during the no load?

Hi, why is the plus vire going into the cool, would IT work without IT being in the coil?

thank you brst explaination i will try this

Oh, I see that you speak english too. Congratulations !!!

I see that the circuit is similar to the "Joule Thief" circuit. If so, you might need a "negative voltage clip" diode at the gate of the mosfet or the huge negative voltage bursts can fry it!

This works for me but can't power anything with a winding like a motor for example. I had a couple high voltage 40volt led lights that it powers no problem. I see store bought boost converters that run motors, what am I missing? What can I add to the circuit so I don't lose all my amperage?

Verrry goood, nice, thanks , a good day.

i love it

can these be use to supply current to the building that has 90 volt and needs up to 220 volt ?

good explenation sir..

in first i read comments and see de video ,i see that your followers are saying good things about you , i'm gonna subscribe ,hope you keep your motivation and your seriousity , keep it up plz ,and thank you

Can we use any other transistor such as tip 41c or tip 42c for this inverter?I want to attach a voltage multiplier circuit to this inverter.Please recommend me the right capacitor values. I will be thankful to you.

Emejing ... Loved it !!!!!!

can it be used to power up a motor in order to make a self sustained generator?

Hello bro,which supply you had given either dc or ac

What is the practical use for this type of voltage amplification ? trying to learn here !

so your doubler circuit does not need a transistor to switch each capacitor because its ac?

A good explain

is there transformer can be connected to function generator and step up the voltage to 1 kv at frequency 1khz??

What i can do if i neet more current at the output of the circuit. Can i sustitud the mostfet forma 2n3055 transistor? Thanks

I didn't know that tree was a voltage but now I do thanks

this is nice

good job

what is the practical difference between this booster and zvs?

Do I have to use that exact mosfet?
