Stealing from China 5! 12-220V power inverter 

I always love this channel! thank you so much

I would prefer AC output. This could be a could circuit for powering up tube circuits though.

You can't say you stole it from China because they stole it from someone else. Btw. Good video.

Beautiful work, dude! Really nice project!!! 😃

I liked your project thanks for sharing. I have a question you can ask another converter based on this 24v or 48v dc at 220. Thank you

Thank you for this, I tried it, and it worked, and it regulated the output well. The only challenge was mosfets heating up excessively when I loaded the output with the bulb

Can you design inverter with ferrite core transformer to run any kind of load, specially inductive load

wow gracias por ese dato compañero..me sera de utilidad...jejeje para modificar algo parecido..

excelente desde Colombia soy un seguidor de sus publicaciones gracias

Can you make a video of a pure sine wave inverter? Thank you!

interesting. I added a feedback loop to the "1000w" version using a tl431 and a pc817 in a similar fashion to yours. I found that when the duty cycle was less than 49%, there was much ringing on the transformer and the fets got very hot. it's likely your transformer has enough stray inductance to avoid this problem, or your control loop is better.

Do a video on magnetic core selection. Talk about different magnetic materials from EPCOS and Feroxcube. Can you do a EEVblog style whiteboard instructional + practical video?

what changes do I need to make the circuit work with 24v instead of 12v apart from transformer primary winding and mosfets with suitable Vds ?

Привееет не думал что у тебя есть еще один канал👍

Do you have any information for me about ferrite core to use for inverter so the mosfet don’t get hot on second on any load

Make a board for the egs002 It is a cheap true sine wave inverter controller board

Thanks a lot, I have made the circuit. Its working perfectly

What is the primary wire gauge and how many turn used

What about the transformer,windings secondary and primary voltage and resistance ?

obrigado amigo ! com isso consigo fazer um conversor de 24V para 12V 1000Watts ?

please make a SMPS with sg3525 of 1000w.

@7:51 how do you design a transformer can you explain a little of it! Maybe make a video or if you have one can you share the link? Thanks in Advance!

0:45 - 0:50 imagine connecting a digital clock to that

can this be modified to 400-450V by just replacing the zener diodes?

i ve tested your circuit the the voltage stabilization doesnt work please review

Tại sao khi tôi muốn ổn áp ở mức 330v tôi sử dụng nhiều diode zener 47v ghép lại thì điện áp rơi trên opto lên cao

Its a good desing but it needs snubber diods and a snubber network to keep back inductance from blowing up youre transistors like that. As for short protection try a few fets with there bace cenected to the positive of the output through some rrsistors soo if a short acures. This causes the output voltage to drop witch causes the fets to shut off.

Very nice 👍👍 I download the zip file and schematic open but PCB lay out not supported in my computer. Please tell the file format details . Please.

Porque no usaron el mismo transformador?

I have transformer but i need any frequency?

Help plz. Transformer winding data show in video primary data no show help me

Can you tell me 20amp 220v AC motor speed control circuit?

Do you write transformer winding numbers and wire diameter,

I also made this thing by watching your video. But it is consuming 0.90 amp current without load. And MOSFET is heating without load.

can I use a circular core

i connect a led bulb to it and it burnned in few second but other one just work fine

I like to set up this project. Here in Brazil is Very Used.

Can I replace MOSFET to IGBT ??

Can I use IGBT please reply mam

Great project! But please ... make this project with TL494 IC because SG3525 is hard to find in my area.😊😊😁 Thank you!

can you explain why this inverter's output is rectified and filtered (DC) ?

No skin effect on the wire because frequency is too low….should use a mosfet driver chip to reduce load on the 3525,

selamlar paylaşımlarınız çok güzel bilginize ve emeğinize sağlık teşekkürler..

Have you tried using transformer app you recommended? It gives nonsense results no matter what I enter like 'number of primary turns 0'.

Secondary DC to AC conversion H bridge please ...

Not all Chinese mosfet or bad I brought some hy4008 and irf4110 and they work really will they say it’s original it looks different from fake mosfet like it

Where is the PCB layout?

Can I used IGBT ?

Can u make 230v 50hz sine wave inverter

Lets build a pure sine wave inverter now.

I wish to talk with you And want to talk about Lower and higher voltage circuit cutoff in driver Can you help me . Thanks in advance

very nice good video good boy

please share to us the schematic diagram and pcb layout

ty

Nice

Can u make a DC to ac converter

I need a adapter that is basically an USB OTG adapter but it has 2 USB output ports, can i get it from China?

Dc voltage after rectification with capacitors is around sqrt2*ac not the same value.

👍👍👍

Thanks for sharing. I watch many of your videos because you are one of the more knowledgeable DIYers on YT. The following is not meant as a criticism so bear with me on this. The gate wave forms are not good. the turn on is fast but the turn off is very very slow, almost 20uS. Why? This should not happen. Check the wave form of the input current. this can cause heating of the transistor die and hence transistor blows up. When one goes then all of them will go. Does the chip heat up after several minutes of use? If so then with those transistors perhaps you do need to add a gate driver. Imagine how it would work at 47KHz. I also noticed that the schematic says 47KHz but the wave forms period is about 63uS for both sides. the scope says 15.7KHz but that is for both edges so the frequency is around 8KHz. How does this work out for your primary side turns? At this frequency you need to have 15 Turns on each side. I think you are using 4 or 5 Turns, so you need to speed up the turn off in order to run at 47KHz. Secondly the SG3525 is a voltage mode controller and there is no mechanism for equalizing the Volt-seconds on each side of the transformer. The 3525 was made just before current mode control chips became available. If I want to make a low cost push-pull, I use a UC3842 chip (10 for $1) as the controller and apply its output to the 3525. Both chips are very cheap and with a little bit of additional circuitry you can make a reliable current mode controlled push-pull with current limiting and excellent voltage control. otherwise your transistors will blow up.

Higher frequencies (here around 30 KHz) benefit in smaller transformers, but devices, which need 50/60Hz can't be driven by this circuit.

i need a circuit

What will happens if PC817 Get damaged ....??

Complete circuit price Bangladesh

It's good but you didn't show clearly steps to make it

can you give me this file pcb ?thanks

can you make it output as AC 220V 50-60Hz?

I think it can only (strictly) work with SMPS only. Obviously transformer based devices won't work.

10:40 I see few things wrong with this circuit. Gates resistors have too small values. SG3525 can only provide 400mA peak. No snubber network on the MOSFETs drains. Value of the 1k potentiometer is too small to limit the feedback current when zener diodes are conducting and finally there should be one extra ceramic low ESR capacitor near the source pins of the MOSFETs because electrolitic capacitor alone does not have low enough ESR to deal with sharp current spikes during transistor switching.

Outputting a DC voltage isn't the best thing, some examples: this way only two of the four diodes in a full bridge rectifier see the full current, transformers act just like a resistor

Làm inverter bằng IC CD4047

please. response does not work sg3525

I love you 😘

Becouse we need to prove

Zener diode's value

yea those caps are horrible. had a few go like that myself. threw them in the bin and bought panasonic.

pcb layout

Jlc PCB not support u

First comment!!! Great vid as always.

Great video , I’m just learning about these control chips , looking at the data sheet I’m not sure that the SG2535 has any advantage in the non use of a gate driver over the TL494. both IC claim 500MA~ source to sink Actually the TL494 claims 500Ma per transistor and the SG3525 states 400Ma peak per drive transistor. So I think they are both very similar it would come down to personal preference on something like that Those fake mosfets are the dumps I’m sure I have a bucket of them here, makes scavenging worth while in some aspects and Television sets {both old and new} all the more desirable. Edit looking at the block diagram of the SG3525 I can see that the gate drive has two NPN with the output from the bridge of these , traditionally that could allow for a nicer gate drive in terms of on time etc, so perhaps it is better from that point of view. However I’d be inclined to use a built gate driver anyhow so no great loss and probably not a huge difference at lower frequency. Great video

what is the point of doing the "precise" and saying that the Chinese do bad things when instead you give limited information, such as the diameter of the wires for the primary and how many turns, in the downloaded file there is only the diagram and the file for the pcb can not open? It is not a beautiful thing .....

Improper information regarding winding which is the main part. 1) Didn't mention the SWG or mm size of primary winding 2) Not clear how you did primary winding. Dont mind but if you literally wanna make such informative video so you should explain step by step information in order to mislead the viewers. 😐

Зачем ты пишешь по английскому. Только по русскому

3:03 the girl setting the pcb plate appears to be blind...

Please translate to Arabic

You have been buying Chinese stuff all your life, and you still do, but now why do you have to sell yours, they are no longer good, come on ..... !!!
