Very useful circuit I enjoy this video thank you brother.
Man you are a life saver. Thank you so much for the video ❤❤👍👍
Excellent project 👍
thanks to give your idea for everyone
Thanks brother for your bother.❤❤❤❤🎉🎉🎉
Primary (30 Turns) * 3 (AWG 23 = 0.574mm or 24 = 0.5106mm), And Secondary Turns are 26 * 5 with center tap 13 + 13 Use Wire (AWG 23 = 0.574mm or 24 = 0.5106mm)
Very useful circuit, thank you bro👍👍❤️❤️
Good explanation !
Kazi safi bro....
Very nice. Kindly provide some more detail regarding inductors and transformers plz
Keep it up dude.b
HELLO
HOPE YOU MAKE MORE 4KW PULSE SOURCE CLIP WITH OUTPUT VOLTAGE +/- 90VDC.
THANK YOU SO MUCH FOR EVERYONE'S LITTLE KNOWLEDGE
You are the best,thanks much;

Do a similar video on a 24 V 3000watt hi freq. (30 KHZ?) inverter for 220VAC with 4 or 5 pulse transformers, 16 or 20 mosfets, *or just one hi freq ferriteb toroid*, and 4 or 6 IGBTs or Mosfets for the H bridge output, but only using the 2 cheap, china, assembled boards,the SG3525+LM358+PC817, and the EGS002).
Hola, qué cambios debo hacer al circuito para que se alimente con voltaje de red a 115 Voltios AC. En mi país ese es el voltaje que se utiliza. Agradezco tu atención
Helo! Nice video by the way. But I tried to calculate the Np take into account the ETD49 for 50 KHz and a Bmax at 1800 gave me 20 turns. If I take the 30 turns and check for Bmax, it will be around 1200. I found that the cross secționale area of the core to be 1.63 square cm.
Very good tnx
HELLO
HOPE YOU MAKE MORE 4KW PULSE SOURCE CLIP WITH OUTPUT VOLTAGE +/- 90VDC. USE FULL BRIDGE SWITCHING, FOR EVERYONE TO LEARN MORE FROM YOU
THANK YOU SO MUCH FOR EVERYONE'S LITTLE KNOWLEDGE
Could you please elaborate the role of R14, C24 at the output? Thanks.
Hello, does anyone have the PCB file of this circuit?
Well done sir and thanks for sharing your knowhow. Please can sg3524/3525 ic be coupled with 555ic to create or change the output to modified sine mode instead of square wave
is it possible to make +24 0 -24 v or +/-24v resister value and winding count for transformer
Sir can you show me the power supply of class H amplifier 60-0-60+120-0-120 volt 10Ampiar
Sir, show me by making some big SMPS supply which is of more voltage and more ampere.for power Amplifire
Bro make an video for uc3843 ic inverter circuit
Will deadtime increase if you increase R6 resistance?
is it possible to make +24 0 -24 v or +/-24v 900watts
is it possible to make +24 0 -24 v or +/-24v
Ser some supply minimum for Sg3525
is it possible to provide me Gerber file and components list to change from +/-60v to +/-24v
Good video
Answer me this….. what is with the voltage flags …if something is a output why don’t the point out? Away from the source…. Is this normal?
I am looking at a schematic right now and cannot determine where voltage reference comes from… Probably because of the stupid flags not meaning anything
Ahh…vref, is output of chip 5 vdc…still no consistency in these flags
Pasti IC 7812 akan panas karena men setemdown dr300v ke12v
Can i use etd59 this circuit?
Where can I download PCB
Hey i have transformer from old crt TV but there is no data sheet i found on net can i use it.... It's has name bck40
Its most likely a flyback. Has an air gap so cannot be used here. Its half bridge.
Price bro
hi brother , can i make 12 v high current from this scema.... just change Ns right...?
and change ZENER DIODE TO 12V.....?
Yes 😉👍
Sir how to increase 900w to 4000watt?
Sir please make 35 0 35 smps
Schematic diagram pls
sir please upload pcb pdf
explanation is good but your english accent is not very clear.please try to improve your english pronunciation.
hmmm, good try but far from a quality solution and for professional application!
A few things bother me... I'm sure there are better solution than transformer for the 12v secondary, almost same dimensions as the ETD49/54
Then FLOAT 160V + HVDC 320V... no, I never liked that concept and so much current going through one capacitor C29. I don't know how it will behave with the dynamics of the music, with the peaks in the current which can be up to 10 times higher than the nominal current, I always prefer a toroidal transformer over a switching power supply! I have transformers older than 30 years and they have no problem EVER, try to convince me that switching power supply will last more than 2-3 years, and spare sparts... man, avoid if possible
I wasted a lots of time and money on this circuit and I gotta say its a huge disappointment. I have checked many times, everything is perfect just like showed in the video but the output is unbalanced even if loaded with resistor +50v 0 -83v transformer is perfectly balanced, not the problem. The worst part is that its blowing ultra fast 30A diodes WITHOUT A LOAD after a few minutes.
This circuit is a disaster dont even try it.
hello which diode is blowing off, cant locate the 30A diode
AND AUTO VOL PULSE SOURCE, WITH 90 VAC TO 240 VAC INPUT VOLTAGE AND +/- 90VDC OUTPUT VOLTAGE, WITH FULL BRIDGE SWITCHING
THANK YOU VERY MUCH
TH-cam có đó. Làm tốt 3800w liên tục đỉnh gần 5000w
