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 !
@@biohazardmadness1155 I don't know, but I guess a diode with PIV higher than 500v needs to be used. A 1N4005 has a PIV of 600v, but that may not provide enough protection, so a 1N4007, with a PIV of 1000v would be a good place to start! (BTW, PIV is peak inverse voltage).
Very good. You make it easy to understand and recreate. There is more to this simple circuit: The Diode here does not only rectify the AC, turning it back into pulsating DC. But, if it is correctly oriented, the Diode is made to Output only that half of the AC power wave which exists while the DC input impulse from the battery is turned Off. This is the greater power of ambient space quickly reforming the small local magnetic field back into its former unpolarized state. There are some uniquely cool properties to this power. But for normal applications, it is suggested a high voltage capacitor is placed between the +/- Output. And realize, that any output during Input-Off, will naturally not load down the input with extra current (amps). So, there is an immediate efficiency advantage with this circuit, and many variations to experiment with. Good fortune, have success!
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!
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?
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)
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.
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..
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.
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!
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.
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.
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?
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!
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
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?
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.
Hi man, thanks a lot for this circuit, Is what I need for my personal DIY coil gun. My First question is: can I use as input an AA battery of 1.5v for an output of 450v DC, to charge a capacitor of 450v? Second question: is it possible to buy only an inductor of 30mH (as I can see from the label)? I can't find it on line, someone can post a link where I can buy it? Bye
For this video an your other one like this, you should discuss the winding resistance or number of turns on the indutor(secondary). Or even a inductance measurement just to give people a better idea of what to look for when choosing an inductor or transformer. How many windings do you think is on that secondary output coil?
Hi, Thanks for the video. I was wondering if this can be used to make a spot welder for batteries to make battery packs. is it possible to do that?? thanks.
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.
I assume this could be used to charge a capacitor? Am I wrong? Need some way to charge a high voltage capacitor? I originally was gonna try a boost converter

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.

This circuit produces spikes I have simulated it then how it produces AC as u said?
thanks
instead of disassemble the fluorescent light, is there a part number available for the coil?
awesome thanks for sharing - great video.
Awesome work

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

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
this video is about reusing HV coil. you can use this driver to drive any transformer
How did you determine which is negative and positive output from the bottom coils? Where do you run the output from?
Hi Ludic I really enjoy your meticulous explanations. What country are you from ?
Which cap and divide you use to multiple current 500 v to 1000 v ?
What is the practical use for this type of voltage amplification ? trying to learn here !
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?
with a load you have a voltage drop depending on the load itself
Great video! What would need to be adapted to be able to supply more than 2W? Say 100W?
Wonderful explanation. God bless u
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!
you need 12v zener, because no matter the polarity mosfet gates and inductors dont mix well
Put a scheme or circuit
Hi, why is the plus vire going into the cool, would IT work without IT being in the coil?
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
@Ludic Science can we use normal electrical tape to isolate the two winding of ferrite transformer?
Thanks for your vids
can these be use to supply current to the building that has 90 volt and needs up to 220 volt ?
Thank you so much
it would be great if you showed how you made that VOLTAGE DOUBLER at the end of this video as well

Best.detail and good
is there transformer can be connected to function generator and step up the voltage to 1 kv at frequency 1khz??
if i want to get AC, do i still need a resistor? does the resistor changes the frequency ?
Thanks you for good teaching 😊

Did it work?
I think this is similar to slayer exciter circuit, except the base connected to primary
Mind if i ask men.... but what is the formula on getting the voltage limit of the inductor coil...?
muchisimas gracias lo voy a intentar hacer en mi casa para unos proyectos, sigue asi, gracias
so your doubler circuit does not need a transistor to switch each capacitor because its ac?
correct
Really nice! :)
Oh, I see that you speak english too. Congratulations !!!
What i can do if i neet more current at the output of the circuit. Can i sustitud the mostfet forma 2n3055 transistor? Thanks
Hello bro,which supply you had given either dc or ac
For this video an your other one like this, you should discuss the winding resistance or number of turns on the indutor(secondary). Or even a inductance measurement just to give people a better idea of what to look for when choosing an inductor or transformer. How many windings do you think is on that secondary output coil?
Right 500÷3=166x10(primary)=±1660 turns
I'm guessing you will have about 30-50 Ohms of winding resistance.
Hi,
Thanks for the video. I was wondering if this can be used to make a spot welder for batteries to make battery packs. is it possible to do that?? thanks.
it is possible with capacitive discharge. you could simply use a fuji flash camera circuit. add capacitors in parallel as needed.
can you tell me how much ampere should the inductor be of?
Please on what gadget do we need to use 500V?
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.
Hi what about current? can you make a circuit that can give from 3V to 42V with 10A? thanks
I assume this could be used to charge a capacitor? Am I wrong? Need some way to charge a high voltage capacitor? I originally was gonna try a boost converter
That was great .i once tried to make taser transformer but i fried my transistor all the time .is there any solution .
This is basically a Bifilar Coil. You could have gotten an even higher output if you found the resonant frequency of the center-tapped inductor.
OK it's very nice
Right side how much turn?
Left 10 and 6.
What is the Right turn?
Thank you.
nice tutorial thanx
What voltage type are we boosting to? 500DC or 500AV
Could any one tell me what is this demo for, the mosfet as a switch?
Sir can we use LM805cv instead of mosfet u used
