Can you pls tell me which software did you use to design the PCB of this project?
@uaart23 PLEASE DONT KIDS, He's joking because it's too dangerous to use on a fridge
Why to convert DC to AC then AC to DC then DC to AC when you can convert direct DC to Ac in one step with module
@@Woodz_007 He only replies to those who compliment him, to criticize him or to those who don't want to pay he doesn't answer
Nicely done. As digital board designers we tend to think of a trace as a line from point to point. (5mil here) However if you look at analog boards, and especially audio, those PCB designers seem to take the opposite approach and create isolated islands, leaving as much copper as is possible. So they simply create design rules mandating clearance and "flood" the plane as much as possible. This of course gives you more current capacity. The boards conduct heat better and will etch faster. Surface Mount technology originated in Audio/Visual markets where single sided boards were dominant An all SMT board needs no drilling or vias. Just mentioning this because there are many ways to do something right and its a fun exercise to consider the options.
the diode you are using is not recommended for high frequency, try to use a high frequency diode like mur460 or her408, if you use a bridge diode as in the video it will usually heat up quickly and break easily and is recommended for low frequency. and if the circuit works at 20watt even without load try to add a 20k potentiometer on pin 6 ic sg3525, then try to connect it to the power supply, then rotate the potentiometer until you get the lowest standby amperage, usually the problem occurs in the mismatching of the transformer and pwm frequency, pin6 on the sg3525 ic to adjust the frequency, and it could also be a problem with the high voltage 300v output diode, try using an ultrafast diode.
You are engineer or repair electronics
I think a great addition to the project is the ability to select voltage and frequency. It would really be useful when testing equipment from foreign countries, like testing 120v/60Hz appliances in 230v/50Hz countries.
For 120v the output DC voltage shout be half, or around 170-200v, and to change to 60Hz, you only need to make a jumper on the control board, there are a lot of information about (the board is egs002), you also need to change the voltage divide om the output so the board doesn't think it is under voltage or something like that...
Yes, the driver, on the back it has a few pads. Bu shorting JP1 you change the frequency to 60Hz. Check here: 2.bp.blogspot.com/-dCnZ-R7fvxg/VxjjoYuf0TI/AAAAAAAAAYQ/beKxILumNvIr-FTpv1uquqtYu6-A6aWiwCLcB/s640/jumper%2Bsetting.jpg
@@ELECTRONOOBS Could another frequency be set instead? Like 62.5 or something? That would help in some solar panel microinverter applications..
@@icarus901o be complete, for testing other devices for exemple, an UPS should be able to provide 99V to 132V @ 54Hz to 66Hz (for 110/120V +/- 10% @ 60Hz +/- 10%) or 198V to 264V @ 45 to 66Hz (for 220/230/240V +/- 10% @ 50 or 60Hz +/- 10%) with continuous variation on both voltage and frequency.
That's a very hard technical challenge ! 🖖
Edit to add : that's why some power supplies are rated 99 to 264V @ 45 to 66Hz 😉
Consider Aviation, with 115/120V @ 400Hz +/- 10% too 😅
@@ELECTRONOOBS is it possible to used ferrite core because its working on high frequeancy and our output is 50Hz only can you clear me
i am very happy you made this project. looks like it works well
Glad you like it!
Thank you electronoobs ,this was very insightful and entertaining.
Good luck in further projects.
I appreciate all the work you've put into your Videos and the free stuff you share.
I hope one day to be half as good as you with electronics
I'm so excited to see this. Nicely done
That sine wave looks beautiful and perfect.
Thank you for this awesome project.
You have add to my source of knowledge.
Good job. HIghly appreciated for such a great project.
This project deserve a like 😁.
Was waiting for a long time for that project❤❤🔥🔥
Happy to deliver :=)
Yes, these are kinda nice but watch the bootstrap voltage on the gate drivers.
I blown many ir2110 and mosfets before I scoped the gate drivers power rails.
My inverters were randomly blowing when idle or at power-off. I was deep in the dead-time settings but missed the fact that the gate drivers were ringing like mad and spiking to 18v regularly.
Lowering the esr on the bootstrap cap did the best in lowering the ringing amplitude. Zenners are the last frontier.
My measurements shown 30-40ns long spikes...
I'm curious why you didn't add a bleeder resistor across the HV caps. Definitely love this project. Thanks!
it takes efficiency directly away from the unit
@@SteveWrightNZ
DC Caps with a voltage over 50V should be discharged in less than 5 mins, it is a normative point. This UPS is a great project, but could not be sold with its current schematic !
@@SteveWrightNZ bleeder resistors take a few milliwatts. Percentage-wise it's 0.0x% wasted energy.
@ No I dont think so. Do the math.
@@SteveWrightNZ oky-doky! Let us *do the math!*
Bleed resistors for the mains charged filtering caps are in the 500kiloohm to 1.5Megaohm range.
A capacitor in the hundreds of microfarads stores many Joules if energy but many Joules are very few Watts/hour.
We want the cap to be discharged in a few minutes.
The voltage across the capacitors is in the 350Vdc range for 220Vac.
I=U/R
350Volts/500000ohms=0.00064amperes
or 350v/1000000ohms=0.00032amperes
P=UxI
This gives us 0.00064Ax350V=0.224W
*Two hundred and twentyfour milliwatts of lost and wasted precious power in a killowatt range power supply.*
Here's your losses.
Do the math not thd meth!
Looks lovely! Very good reference for when I have to go make one.
Please do make a upgraded version of this with more power and also continue making such great content. Much Love and support from India
amazing work! 🎉
Really Good Video Sir, Your great teacher...
Amazing work! Keep it up!
Even designed one. its Great, like this! I was waiting !
thanks for posting this one.
Amazing work 👏
Well done. Great project
Best I understand your effort great job ❤
And it looks great. Nice work.
Thanks. Good work.
Excellent tutorial - thank you
Very nice design, i was wondering yor feedback for the SG3525 circuit, i noticed that the pin 2 was pulled to ground through a 10k resistor only, how does the circuit regulte the voltage to 380v directly
I’m pretty impressed that you’ve done this from scratch 👏 The 12V input looks a little on the the slim side if you were to go up to 500W - 40+ Amps doesn’t seem likely with that ready made board 😬😳
Nicely done ! I've made an inverter few months ago based on the same ship, the most challenging part to me was the inductor filter, I struggled alot to find the right material core (it has to be a low permeability core), adding to that I had to reach around 3.3mH inductance, but after 80 turns I almost had no window area left to add more turns and I only got 1.2mH, So I had to compensate that with a higher output capacitor ! It was so far my best project and the satisfaction you feel once you get your output sinewave is just priceless ! I would like to mention a last thing, do not trust the readings of the LCD display it's fake !
Hello, is the LCD display of no use at all?
@@mephistowalzofficial9970 Maybe for decoration 😅😅 I would not recommand it ! My advice to you is that you should not trust the displayed values on that lcd
Have you documented your work anywhere? I'd like to see what you've done?
Is it working properly bcoz i always got brust my igbt and egs module after few minutes
@@samcreation9225Well it's not really robust but you can improve it performance, usually what burns first is the ir2110s chips I recommand you replace it with 4xtlp250 mosfet drivers, it is also recommanded to isolate the control circuit from the power circuit GND, also make sure that your mosfets are of good quality and can withstand the voltage and current ratings of the circuit ! And finally use a proper heatsink (the bigger it is the better is) and a fan if the mosfets get hot alot !
I really get the knowledge about how these ferrite core transformers work on inveter
Excellent work Electronoobs.
Thanks!
Cordial saludo, muy bueno su video, que modificaciones se hacen para construirlo de 12vdc a 120vac
Awesome project 😊👍
Such a super good video, thanks!
Great job! Saludos 😄
Hi Thanks for video, Could you assist us in identifying the changes we can make in the current design to increase the Watt value? for example 1kW , 5 kW, 10 kW .
Wooow is Cool PCB design
Thank you very much for this educative video.
I want to build the exact same circuit using your provided files but first, I want to verify the parameters of the shunts you used.
Inspiring video, thanks for making it :)
U welcome :)
Great job!!!
Felicitaciones compa;ero!
Cool project, great video!
I would have liked to see a cost breakdown if we were to follow your lead and build this project.
Buen trabajo
me gustaría más detalle de las partes y funcionamiento
A trick that will not need a redesign is to mount the IGBT's and other fets under the board so that you can mount to a Heatsink like an amp or some of the grid tie inverters this will allow more room for heat sink thus better cooling as those caps behind the IGBT's are in the way, but other then that very clean board.
And the caps themselves are too close to the transformer, they won't last long with that heat, maybe they should be on the other side too !
Great explanation
Great video. I really wanted to have a block explanation of an inverter. By the way what was the inductance of the larger Inductor and is it super precise on its mH?
That was amazing
Thanks man
!
what is you use really low resistance mosfet instead of the igbts and low voltage drop diode for the rectifier
@10:04 that perfect sine wave curve is so satisfying to watch
I took a look at the schematics and... I think that the bridge rectifier is not rated for high frequency, that may explain the low efficiency at light loads, and may cause catastrophic failure at higher loads.... The ideal is to use fast recovery diodes...
And for 500w, that shunt resistor will do nothing I think... The voltage drop the egs002 board detect is 0,5v I think, and for 500w 0,25 ohms should be enough for 2amps overload at the output
Also it isn't present on "BOM" list
Thank you for this great video.
I have wanted to make a few of these for myself for sometime but didn't want to pay $200-300 for one quality full sine wave inverter.
Hi Electronoobs congrats!! keep up the good work!!!, what do I need to modify in order to get 120vAC in the output?
What are the values of the "big" output inductor and capacitor?
How did you calculated them?
Good Jobs Sir 👍🏼
Hobi Elektronika Coming 😊
It's always good to make a project and prototype to learn mistakes and improvements that you would need to make.
Let us hope you follow this up, and some of the other projects that you didn't finish or the series that never happen over the years.
Keep up the good work
A good project indeed. Could you provide schematics in some more editable format?
Andrei,
Another fantastic project. This was very educational and interesting. I began to wonder what would be necessary to convert to 120 V output at 60 Hz since I live in the U.S. I saw the comments by Victor Silva and yourself below. So that pretty much answered that question (frequency sounds easy with voltage being a little harder). Thank you for creating this wonderful project and sharing it. It was very enjoyable to watch.
Frequency is easy to change. For the voltage, you would need to supply the IGBT bridge with 220V instead of 380V. That's why the transformer has 2 outputs. But you will need to change the PCB so the 220V is connected to the IGBT instead of 380V. I haven't tested this yet so this is only a recomendation. Have that in mind!
I understand. Thank you!
Awesome project. How would you make it such that can change the frequency (1-10kHz) and the voltage (1-220v).
So like a fixed voltage power supply but variable voltage bench power supply.
Nice project.
Your effort in creating this module is commendable, and I'm truly impressed by its performance. However, I'm curious why the LCD displays zero amperes when a 100-watt load is active.
Muy bueno !!! Hace tiempo quiero hacer uno pero con mucha mas potencia !!! Abrazo desde Argentina
Nice 💕💕💕 I love it but sir what for short circuit protection I need any solution for Short circuit
Awesome project. Thanks for sharing. just couple of questions first about egs002 it requires 5v and 12v to operate but you used l7815 regulator is there any reason for that??can't we use l7812?? Second question is about capacitors used for the first stage, you used 450v 100 uf capacitor. Can we use same capacitor that you used in coil gun project, the fat 450v 680uf one?? I just have few of them around😊. Thank you again for this wonderful project
Awesome man! On your way to making a all in one welder that can do the aluminum DCEN & DCEP offset waveform control for the balance function welding. Like for weld penetration and oxidation removal. That seems to be the most expensive function and doesn't seem that complicated once understood how to control the waveforms.
Soft are hard starting capacitors added with a bleed resistor (I forget if they come with already) might stabilize the startup slight brownout?
nice, i wish to build a portable power bank with ac port, now i can use the more compact version inverter
So if you were to use a boost converter to step up efficiently to 220vDC you can increase your efficiency right?
Does the spwm board take voltage feedback so that it can compensate for load variations? Would be also cool to add a digital control filter to simulate the lag of a generator so it can drive larger power tools.
Could you cover more detail on the transformer you used, or how to design on correctly?
Wasn't it possible to place discharge resistors between those capacitors?
thanks bro
Nice video 👍
hi i like your all videos , I have a question, how did you calculate the efficient ? i think that is of 66% and 34% is conversion, is It ok or I'm wrong ? thank you
All that is needed now is a huge lithium ion battery pack with BMS and charger, and a transfer circuit with solid state relays then it will become a reliable UPS unit and due the full sine wave it will not make noise or interference. perfect my friend, great job. (note: in places like my country where blackouts are common that device is a jewel)
You should add a way for the capacitors to discharge slowly and an indication that this has (not yet) happened. A large value resistor(s) and a led maybe?
Well done , can you make a small video on how to parallel DC-DC stage transformer to increase output power to maybe 1000 watts or 1500, thanks in advance
Could you increase output power by using higher voltage battery so you don't need that high of current. I have many 72v batteries but there aren't many inverters for them available.
Nice Project! I built your project and the inverter creates 220V but the transformer of the high voltage generator makes loud switching noise. Also i´ve noticed that the original board of the high voltage inverter has two different resistor values. For R24 you are using 10R. This Resistor has a value of 100R on the original Board from aliexpress. Also the Value of R23 differs from your design. You are using 33K and the value of my board was 3k3.
Do you have any idea why my HV converter makes so much switching noises?
Thanks in advance!
Great project! Could you please make a video in which you explain about the working of this circuit, boost section waveforms on load, and output section LC filter design with respect to frequency.
Thanks for the video❤.
I have actually designed the booster section of the inverter which was capable of 250w but the output voltage drops when i put the load on it from 230v to 170v even with regulation feature of sg3525. If you can please make a video about this topic.
Thanks
Ďakujeme.
Your videos are amazing!
Hi Sir Great Job Thanks for sharing ... Please share Transformer details for High Voltage side .... and Output Inductor values for more helpful Thank U.
Nice work 🏆🏆🏆🏆
Thanks for this awesome tutorial, schematics and board designs. You are always awesome with your imaginations and knowledge. Will you be kind to enlighten us with the details of the HV transformer and coils you used ? Anyways great efforts and project . Thanks a lot !!
The transformer he did mention was removed from a board he purchased on Ali Express. But he did not give details on the other two magnetic components. Perhaps they were also purchased somewhere, although he may have harvested them from the inverter he was repairing for his relative.
what if you connect this inverter straight to the mains ?
I would love to see making of a grid tie inverter, connected to the mains
Couple of component and layout pointers. I think I know where much of that 20 watts was going……I bet that full bridge rectifier was hot as hell….they are designed for low frequencies only and commutate far to slowly for use off a high frequency switchmode transformer….iuse four fast diodes like RF1005TF6S or equivlent….and put them on a heatsink.
The layout issue was those two 100n caps BEHIND the inverting H-Bridge MOSFETS making it difficult to get a good solid heatsink mounted there, if you move those to the front or put them underneath, then a heatsink can be mounted to both the boaed and FETs. Don,t forget the sil pad to isola te the backs of the FETs from the heatsink.
Cheers fron Tasmania!
Please make a video about sg3525 and the pulse transformer winding. Burned a lot of mosfets because of those.
What a nice. Sir electronics👍⭐⭐⭐⭐⭐
Good work
I got an epever inverter, its a chinese medium quality brand. Although its a good bang for the buck I wouldn't use to to power life support machines lol. Is there a way to overengineer homemade inverters for reliability and/or redundancy somewhat cheap?
Great project, can you create a VFD based on this circuit?
Could you also add the link where you got the 400VDC driver?
Can the output section be used to put in 24VDC and get out 24VAC?
thanks for the great video. why did you use the transformer before the circuit and not after the AC voltage was generated?
The transformer seems to be used to provide a boosted voltage, from the 12V at input to the several hundred bolts used to produce the sine waves.
Hmm, shouldn't there be physical separation (e.g. cut-out sections of the board) separating low-voltage and HV sections? I'd definitely want to make this if it had that and other safety features)
Pretty cool project, there is a lot of room for improvement! I myself am starting a video series on inverters and my first video in this series is live! 📺
Use a better transformer, and a smaller one to minimize losses, run at even higher switching frequency with really good silicon or possibly even something like GaN
Use a split secondary output to implement a full wave converter rather than full bridge, minimize saturation voltage drop losses of IGBTs, or use GaN or SiC to further reduce losses
Use synchronous rectification on the HVDC generation stage, to eliminate losses from a traditional diode bridge.
Don't have the capacitors butted right up against the full bridge rectifier and transformer, these components get hot
Heatsinking looks like more of an afterthought
Did you take any safety measures in your board design? Would be nice if you go into minimum track width, spacing and creepage.
this is DIY proyect not a commercial one, leve the detail designing for the profesionals 🙂
Definetly. I don't think that he calculated a single parameter.
Greets from a "professional".
Can u pls give me more info about the transformer
Like the number of turns and size of core
can you up load the diagrams for voltage ,current ,frequency etc ? thanks
