The repair steps
-Check the fuse
-Check mosfet - Use a multimeter in diode mode. If a value of ~ 500 between pins D and S is a good mosfet, otherwise, replace the mosfet.
-Check the DC filter capacitor 12 - 24V
-Check the 310V filter capacitor
-Check fast diode
-Check PWM signal from SG3525 or TL494 (about 35Khz)
-Check the H-bridge mosfet (310VDC - 220VAC)
-Check the SPWM module and driver ic.
Replace broken components and test with 12 - 24v power supplies at 1A current. If the fault is still, the 1A current cannot damage the inverter.

Which is better, de-solidering the components and reading separately or reading the components directly on the board ?

With your help, I was able to identify 6 defect mosfets. If my inverter works after replacing those, I will buy you a cup of coffee. 😀
Boss how to repair power fault my power inverter after 5mins..
Oh god, thanks alot for the video, 100% content 0% nonsenses. Tired of all those 99.9% talking nonsense but 0.1% contents. Support your video !!!
Wow - lots of parts to swap out - something I or 99.99% of people would never do..great result though.
I only fix motherboards or power supplies if simple stuff like blown capacitors and maybe diode pack or fuse. Thanks for the detailed breakdwon though...very informative.
Nice work and right- to-the-point video. Just Great.Please post more like this. Inverter repair shops want $$$ for repair like you did. 🎉
This is hilarious. I'm still waiting for delivery on a 2KW 72v dc to 220v ac unit like this I ordered about a week ago. May be I should have ordered another filter cap and some MOSFETs to go along with it. LOL
what i realize when working with inverter as a newbie is an osciloscop is almost a must, working with inverter and only has a multimeter is rather painful
Great Video Thank You God bless!
Thank you very much, people like you give me more motivation to make videos.
Very interesting especially checking pwm with oscilloscope, what needs to be inline to stop damage , your video is very instructive for repair . Thankyou for posting
Excellent video. We would like you to continue publishing such videos
I will try
You are great ! Thanks to you, I have repaired my inverter !
You make repairing an inverter so easy i have to say you are blessed with a lot of knowledge...!!!😲
Good technician
Superb repair. I love that you show what you're doing and why. It's very logical, and so satisfying to see the device working. You're one of the very best doing that on youtube (or I haven't checked well enough :D)
I also like the concise but very informative text you put in. Simple but super effective.
Thanks bro
@@PhdHung 18:45 where are fuses that you removed first?
AC work bare foot, you're a brave man ;) Loved the video, thanks for sharing!
So much knowledge being shared here. Thank you
That style of clamp used to hold the MOSFETs and diodes to the heat sink is much more effective than just bolting through the mounting hole of the TO-220 package.
Anyway this took to long to figure out. For this guy anyway. I found three 30 Amp. Fuzes just like the one's in your car. And it was in the middle of the inverter and the middle was blown. That was the Jupiter 1500 watt from harbor freight.
Hi the samlex 1500 12v that I told you before is now showing over load. I change some of the mosfet as you told me and now giving me a trouble again. I appreciate very much if you guides me how to fix.thank you so much.
Great teaching
Thank you
i dont quite understand all of it... but this video is very helpful. thank you. you earned a new subscriber. and the inverter is exactly the same as the one im trying to fix 😀
Interesting and helpful but back in the real world these youtube fixes never seem to be the faults i get. ☹️
Hi bro, love watching your videos. Any idea what could be the gauge of the wire for primary and secondary of the transformers ??
Sounds like you have a busy shop, good video thanks, hope it was worth it, a lot of work.
Hi grate video.
I have 3 out of 4 mosfets blown in my inverter irfb13n50a but they are not available. I dont no how to deside an alternative. What do u suggest
👌👌🌹GOOD TICHING KARTE HO AP THANKS 👌🌹💖😂😆
Excellent repair!
This is great, I have a question for you, can you convert a pure wave inverter from 24v to 12v?
Nice repair skill. Thank you very much for this video. Can you do project on power supply to do inverter test for 12v to 48v. It will help where no battery is available for testing inverter.
Better than the best. Full details, no fuckin back ground music. .
Inverter w/ ferit transformer is more compact in size
Thank You, Master Zirconium
Good effort
You are a magician,congratulations ! I'm impressed
Thanks
You are just amazing...I never skip ads on your videos
Thank you so much
Good repair very complicated. My Inverter only burn 1 MosFET.
alat e sampeyan iki lengkap yo mas, pinter sisan... pancen joss :)
Thank you for sharing this, I have a 3,500 watt inverter and I wanted to replace a couple of MOSFETs . The part number of my inverter is FB38N20D P038D and I found one on Amazon with part number FB38N20D P826D, could I use these or are they a different number all together?
I love ur explain sir very 👍 Good sir
I personally would've changed the other two MOSFETs to match the new one.
BTW good job
Thanks
Dear friend use small peace of silicon tube to the de soldering pump bit. U can use it for ever
Great video, but how many folks watched this thinking they actually could accomplish a usable repair but now realize they wouldn't get past the fuse checking/changing?
Very good
I want to ask, how if mikrokontroler pwm pure sinewave is broken, can you repair that, because ic pic16f716 must be prorgramable first before we use in the kit
Excellent Bro you look a high level professional. Keep it up
thanks bro.
Having tested the mosfets like you have shown, a couple beeped which indicated they are burnt.
However a couple only beeped on toucing one pin but not the other. Does this indicate these are burnt as well. 🇬🇧
Fascinating video.
My AIMS 2000W inverter cuts out at 440W. Any thoughts?
Today, I bought a broken 2000W inverter from a second hand store. I will show you how to fix it.
Share us such a beautiful full sine circuit Master's health
Yes, I will design it, wait for me
@@PhdHung where are you from?? Bro
Can you share me the second hand store, please?
Envie seu zap para mim ou ligue para mim para poder ver o preço desse produto que eu estou necessitado desse
Good sharing teacher
الله يعطيك العافية
Wow! You are amazing, great job! Greeting from Brazil!
Thanks so much for your valuable information
Hello, nice repair! I have the same inverter with the same mosfets broken, but unfortunately I have no pwm signal to the mosfets, and there's no 5V present (display and 12V are present). Where does the 5V normally come from? 03003A?
please which is best mosfet among irf1404 and 3205. please explain to me
Beautiful work!,Thanks for sharing it!
Awesome job Weldone And thank you 💓
I have a question, What are the correct measures of the spwm signal? I mean what are the limits? Thanks for the video!
Very good troubleshooting
Hello sir, I have a 2000w modified sine inverter. The AC voltage is 330 v and one of the 400v volt electrolytic capacitors at the output starts to heat up after a few seconds. Where should I look for the problem? I would be glad if you help
Awesome work!
Nice video👍👍👍👍 where do u get your electrical components?
@ 19:02
So you don't put that white industrial grease on the mosfets (& on the silverish rubber pads) ? 🤔😕
Thanks !
Hello 👋. Thanks so much✅✅✅✅✅✅🌻🌻🌻🌻🌻🌻🙏👋.
Hello, can you make it with lcd indicator for monitoring?
Excellent
i Have a probleme with a 800w 12v pure wave inveter the output tension is between 150-160v but cant reach 220.What seams to the problem from your experience ?
Very good video
Please what power source did you use the powering the inverter?
Buen trabajo exelente
Good job !!!
Parabéns gostei
Beautiful and straight forward repair. I burned a track from the on off switch of a 1500 pure sine wave. I was trying to attach an external switch for a battery generator project. Any way I reattached the track and I only get fault light to come on. No fan or power to the inverter. I did notice heat coming from pwm module ic. Could that be my only remaining issue? Thanks a bunch
Yes probably but make sure to check mosfets, capacitors, resistors etc.
Hello,
What is the resistance value in the snubber circuit?
capacity=103j 2kv
resistance=?
thanks...
Super.....U r genius 👍
Very Helpfull Knowledge
Thanks, hope you enjoy it
I liked your techniquei but just can subscribe. Thanks.
Great! Thanks for showing.
Tem como fazer um transformador desse de 12 para 220enviar para me dizer o valor para poder pagar
Nice presentation. Thanks
You're REMARKABLE 👌
good job, for the next video discuss about 12v 2S battery stabilizer = 24v charging
Yes, I will try
If you make 12 v battery stabilizer How about =12v thanks
thank you
what a amazing work good job thanku for giving a chance to watch you
really thank you so much
Very professional. Thanks you for share.
Cám ơn nhé :D
Nice work bro, Very helpful ⚡ Bro, I seach the data sheet of Mt7601 wifi mudule and it works for 3.3V, i bought it. But now work on 3.3v, Can I supply 5v? Like what you did on Wireless camera? But on the datasheet rated voltage is 3.3V
Dear Bro, Is it possible to get the Data sheet of the SPWM sine wave module?
Thanks .
I have a inverter. westpoint Power inverter2000watt 24vdc. There are four mosfet output one anymir hot.but in the board that to have sg3524 there are two resistor R11 and R12 in the board was burn.i not see the code color is go.
I like this repair
Thank bro
I like your working style 👍
THANK YOU VERY MUCH !
Hello, first i want to thank you for this great tutorial. I have some questions about how this inverter works. Why there are so many transistors? Which ones are for H-bridge? Are the biggest ones or 75NF75(and if they are not, for what are they)? Also why there are 2 pcb for PWM? The most important question is how it becomes sine wave from PWM, because at the gates of MOSFET's u've got a pwm of 36kHz and some 71Hz on the second ones? I'm sorry for the many question, you are my only hope. Thanks!
The SG3505 control the MOSFETs in the DC boost section and the spwm driver produce the sine wave at the output(The H-Bridge )
My inverter output only 190v with no load even on 13.5v supply what can be the problem?i hope it have adjusting pot to correct the output..
THANK YOU VERY NICE
Saludos desde Colombia. Gracias por compartir.
Hi,Any idea? I put 230v on 230v output of my inverter,when this was on power.I broke my inverter like a foul... thanks man
How is the sinusoid built?
Very nice. thank you.
Awesome. Thanks.
A có nhận sửa k ạk
repairing very good
what is it when the inverter starts ans stops after a second with a beep to work. ?
