- I am trying to improve the performance of my homemade powder coating gun high voltage generator. I experimented with using a motorcycle ignition coil and a CRT TV flyback transformer to be used in conjunction with the high voltage cascade.
Below is the link to my first homemade powder coating gun high voltage cascade module:

Salamat po sa vedio sir .i really like powder coating sir
wlang anuman. may kasunod pa po yan. yung mismong updated na gun
Very educational, thank you
thanks for watching and for being the first commentator.
very good and very scientific
Thanks. I tried to make it as simple as possible for those that don't know much about electronics.
9:18 just remove the first capacitor that is connected to the flyback and the first diode and polarise them right and your multiplier will work even with DC is just like the capacitive droper on light bulbs that enter ac and block dc 😊
I'll give that a try next time
Will you use some resistor at the end like in the old version ? I think it was 1M ohm Resistor
Hi. I tried with and without that resistor at the end and did not see any noticeable difference. I have seen other videos in TH-cam with folks making similar high voltage cascade and they use the resistor at the end to limit the current spike that can destroy the diodes, as they say. So far I have not experienced broken HV diode, probably because I am only using low power, about 6 volts input to the supply. However I do intend to use a resistor at the end as soon as I find about 1M probably use 2 in series. I am only recycling components from old circuit boards and 1M range resistor are hard to come by.
Hi Phil, I followed how to make your mosfet path, but the mosfet always shorts out, can I ask for a detailed wiring diagram and components?
Hi. I saw your email and will try my best to respond.
@@DIYPhil Thank you friend, I am waiting for your email reply, stay healthy
use a transistor BU808DFX
Hi. Thanks for the tip. I simply used what is available to me at that time. I remember I got the mosfet from a discarded UPS board.
hola amigo phil saludos desde argentina. te consulto hice algo parecido con un generador de pulsos pwm y un mosfet , el problema es que si paso de 25 /30 % del ancho del pulso se me recalienta el mosfet . no puedo hacerlo andar a 50 % el ancho de pulso , a que se debe ?
hola amigo la corriente es demasiado alta para el mosfetlo puedes ver a las 10:13 en el video enrollo una nueva bobina primaria para reducir la corriente al mosfet y no recalienta
yo use un mosfet que soporta el triple de la corriente que le puede dar la fuente de alimentación como 100 ampere o mas incluso . recomiendas darle mas vueltas al arrollado ?
@@jidukrishnamurti8114 ¿Qué transformador estás usando? puedes enviarme un e-mail a philipal2015@gmail.com
@@DIYPhil un tipico flyback igual al de tu video
Ola amigo tudo bem com vc , espero que sim, muito bons seus videos , estou montando tb uma aqui no Brasil, mas a unica parte que nao entende seria a do mosfet , vc poderia fazer um diagrama com os valores e nomes dos componentes inclusive do mosfet ? abraços
Hi. Circuit diagram at 2:37. Most MOSFET used in switching mode power supply should work. The mosfet I used in the video is a 2SK3569 which I just recycle from old UPS board. Other people use IRF530N Mosfet, which is a common component.
Very very nice video sir! Super detailed and very educational! I love your videos!
Nagbabalak din magbuo ng ganito pero for the purpose of flock application sir. As of now zvs + flyback kasi gamit ko kaya lang not enough ang static power nya para iapply sa gusto ko.
Im lacking a multiplier, nga lang ang flyback ay dc. So need talaga biyakin.
Pero yung 15kv na coil sir pede ko ba baguhin ang primary winding para pede ko ikabit sa zvs driver ko?
Will that work ba?
May ZVS driver din ako. Nasubukan ko na ikabit yung maliit na transformer wala naman problema.Wala ako binago sa primary winding. Kapag nagka time i video ko yung zvs driver.
@@DIYPhil so no need na po baguhin ang winding primary kung zvs ang gagamitin? Btw, may center tap ung zvs ko uubra din un diba?
@@felmarz17 ahh ganun ba. kung may center tap kailangan mo i rewind. madali lang naman yun. yung zvs driver ko kasi walang center tap.
Hello Phil, can you send me a wiring diagram of this mosfet board you made in this video.
Hi. You can send me an email at philipal2015@gmail.com or message me at facebook DIY Phil. I'll draw that simple schematic for you.
Thank you to share this project!
Could it work with irf3205?
Yes. Mosfets have very similar characteristics. I just use the one I found from recycled electronics.
Are you using both transformers for the gun as well? And the final value of the frequency generator is 700Hz?
In this video I experimented with the ignition coil and tv flyback to see if they will work. The TV flyback will definitely work but it is too big for my gun design. The ignition coil stop working at frequency above 700 Hz. The frequency for the high voltage cascade should be in the range of about 15 to 20 kHz.
ผมกำลังคิดจะใช้ฟลายแบ็คอยู่พอดีเลย น่าเสียดายฟังภาษาอังกฤษไม่เข้าใจ
ถ้าดู TH-cam ในคอมมันมีการแปลอัตโนมัติ คำบรรยายแปลเป็นไทย ที่มุมขวาล่างของวิดีโอ ตอนแรกเปิดคำบรรยายคลิกปุ่ม "CC" แล้วคลิกปุ่มกลมที่ดูเหมือนดาว Settings > Subtitles > Autotranslate > Thai ลองดูครับ
ผมใช้ภาษาอังกฤษเพื่อให้สามารถใช้การแปลอัตโนมัติโดย TH-cam เป็นภาษาอื่น ๆ ได้ครับ
@@DIYPhil ขอบคุณครับ
What diodes did you use? I can only find 5ma 20kv diodes locally.
Also which cascade do you find works better?
See at 6:34 for the second cascade I used 10 kV diodes which are cheaper and smaller. The second version of the cascade with more stages produce slightly higher voltage. Only a slight increase in the output voltage compared to the 5-stage version because I think the ac output of the transformer is not powerful enough to utilize the full potential of addition cascade stages. The 20kV diodes will work. I think in the first version I used 30kV just because that is what's available to buy that time.
Hey...
What the purpose of the mosfet switch?
Is that necessery to add the mosfet switch or can I running without it??
Thanks...
I hope you can understand what Im saying😁
And for the casecade can i use 1nf 2kv??
I can't find 1nf 10kv or 30kv locally
Hi. The mosfet is used to turn on and off power to the transformer primary winding. The 555 ic output pin cannot handle the high current load if you connect the transformer primary winding directly to the IC output pin 3. You can buy HV generator kits that already have the mosfet. Try to search 20 kV high voltage generator kit. It is ready made and you don't have to build the oscillator and mosfet switch separately.
@@colorslaveworkshop2029 I don't think 2kV is enough. However, if that is what you have and you can get that cheap, you can try building the cascade with 2 or more capacitors in series in place of 1 capacitor. That will increase the voltage rating. The capacitance value will decrease but it will probably work.
@@DIYPhil ok thanks phill...
So that the point of the mosfet, so i can use irf 520 driver mosfet module to replace your mosfet version right??
@@colorslaveworkshop2029 yes. it will work.
Sir plano ko po sana magDIY powder coating kaya lang ang mahal ng powder coating machine. Hindi nyo po ba binebenta ang homemade setup nyo? 😊
Boss salamat at naging interesado ka sa videos ko. Hobby ko yang electronics at pagbuo niyang powder coating gun. May mga motor din kasi ako na nire-restore at binubuo. Balak ko i powder coating kaya ako naging interesado sa homemade powder coating. Sa ngayon kasi hindi pa rin ako nasisiyahan sa performance nung mga homemade gun ko. Kaya kung ano ano yung mga sinusubukan ko na setup. Kung sakali na makabuo ako nung unit na kampante ako sa performance, pwede din siguro ako magbuo pa kahit pa isa isa para sa mga gusto mag DIY. Siempre budget meal na presyo. Low budget lang din ako kaya makikita nyo sa videos ko karamihan recycled materials kahit yung mga pyesa ng electronics.
Oo nga ang galing nyo sir! Kita naman naman na tlagang bihasa ka sa electonics. Mahilig din kac ako magDIY. Pero mukhang di ko kayang gayahin mga ginagawa mo kac medyo technical. Goodluck nalng and more power sir!
Es posible usar un generador de pulsos pwm
Creo que sí
Sos un genio y muy generoso amigo . En el otro video podías usar el flybsck sin los diodos en una caja y luego ir con un cable de alta tensión de bujía de moto hasta la pistola y ahí usar la cascada elevadora de tensión. Creo q es posible yo lo estoy armando asi
@@gervasiokuz8926 Sí. No lo he probado pero lo vi a alguien hacer así usar el flyback sin los diodos en una caja y luego ir con un cable de alta tensión hasta la pistola
Soy de argentina Phil me interesa tener el desarrollo completo de esa placa pq acá son incomparables . Existe la posibilidad por favor de comprarte el desarrollo del circuito ?
What is the number of mosfet ic?
Hi. I just salvaged the actual mosfet used in the video from a junk UPS board and did not bother to look at the part number. You can use IRF520 N-channel Mosfet or any mosfet with similar specs.
@@DIYPhil thank you ❤️
