The best techer in this worled really broo tx
Σε παρακαλω τα ελληνικα μην ξεχνας και στα προηγουμενα βιντεο σε ευχαριστω πολυ❤
Thank you for the explanations. It’s very interesting. Have a good evening.
Thanks a lot
Sana çok teşekkürler büyük usta çok teşekkürler.
selam. benim için bir zevktir
Thank you very much Sir for making this video. Sir, please explain the working principle of this Inverter. Thank you very much in Advance. Keep up the Good Work. God Bless you Abundantly.
I had the same inverter card. I couldn't find the fault. Finally I found it. I changed the mosfets and it didn't work. Then I changed the lm 358 integrated circuit. The problem was fixed.
Excellent thanks for sharing this informative video keep sharing❤❤❤
Good job, thanks for share your work
Perfect 👍
Nice sir👍
Thank you sir.
Aleykümselam ve Rahmetullahi ve berekatuhu.❤👍

Sir thank you for this video.
Please can you make a video explaining the AC hybrid circuit of this inverter.
I have one that has problem with the AC side
Me too ... Have you been able to fix it?
Mine has 290v at DC capacitor but no AC output
I have this exact inverter, no AC output, 290v dc present at the capacitor and all mosfet tested good
You need to check H-BRIDGE driver ic TL494 OR KA7500
this section converts 290 dc voltage to ac
Pls make a video of how to do that. I started repairing this type of inverters after i watched your video of how 3000va inverter works. But you have not explained the output section pls
ما شاء الله تبارك الله
Salam Aleikum. Very interesting topic. Can you please explain the following issues:
1- on low side often only one mosfet get hot, the other stays coo'.
2- explain to me how H Bridge works in pair with PWM.
3- Often half output voltage is obtained, not full 220vac.
4- explain what are the tasks of the LM358.
5- can you share schematic to understand where are the vo'tage checkpoints.
Thank you & salam aleikum.
Your video is insightful. How does the the secondary of the transformers connected ? Is it series or parallel ?
I am aware the primaries are connected in parallel, what is wrong if I connect the two transformers output (secondary) in parallel as well ?
best regards
most of time these are in series connected
@@HaseebElectronics
What if I connect them in parallel ?
Hi Sir , could you please make a video on how to differentiate between the original and fake Mosfet ?? Thanks in advance !!!
Good
Good day Dear Ahraf, on a H Bridge of power inverter, i have always mosfet 1 (high side) and mosfet 2 (low side) that burn while 4 and 3 stay ok. Please note that they burn ONLY WHEN I TURN IT OFF, when ON, all is good.
When i use only 3 mosfets, none burns (1,2,3 or 2,3,4). I checked on the scope, signals are identical and voltage between gate and source are the same for low and high side. I am running out of mosfets and i would like to fix that inverter, any idea where to look at ?
Thanks.
Pls sir explain the hbridge section
👍
sir h brige side pa ap ny diffrent number 20n60 use kyia hai is ki wave shape our frequincy kesi hogi oscilloscope pa nhi dakhi ap ny ????
please explain me hybrid inverter with schematic diagram. how does it work. thanks a lot.
We appreciate your work Sir,,,,,I have a question outside this......"what does,A,B,C and D stands for in the following ICs,,,8002A,8002B,8002C and 8002D,,,and finally can I substitute let say 8002D for any of the above and so on?
can you please mention write complete part number or
its use, i mean in which circuit it is being used
@@HaseebElectronics Hello, The 8002 series is a class AB audio power amplifier designed for low power devices. The 8002(A/B/C/D or D) eg 8002A or 8002E is the skeleton part number since the other may contain the manufacturer eg MD8002A or LTK8002B.
@@HaseebElectronics I want to know the significance or at least the variations of 8002A,8002B,8002C,8002D and 8002E.....for replacement purposes. From the internet I was able to find out that the equivalent of "8002A" is LM4871 or TDA2050.....,,,,, Now my concern is, let's say I have a damaged 8002B ,and the ones that are available in my stock is either 8002A,8002C,8002D or 8002E,can I use any of these to replace 8002B and vice versa? Secondly kindly assist me with the equivalents of 8002B,8002C,8002D and 8002E...
Sirji...what is the use of that 10nf capacitor please explain
it is output filter to smoothen the square wave (output of H-bridge). it tapers down the 90 dgree shape of the square wave into a little bit linearly rising / falling signals
would you please inform to me an expert for ultrasound machine repair sir?
Please explain the working of this circuit
Vi amer inverter output normal volt ki kore thik korbo
"This Red and this Black wire are positive and this Red wire here is negative." The manufacturer needs to go and stand facing the corner and think about what they've done lol. 😩
some manufacturers design things without any quality standard. and it creats a big headache while repair process, if someone have faith on wire colors codes. so that headache will never be cured with any medicine because the reversed wires in the equipment will reverse the wiring of the brain 😂 😂😂 😂😂 😂😂 😂
@@HaseebElectronics 🤣
Hahaha

aap Urdu videos mere urdu channel per dekha karein
Haseeb Electronics Urdu per
99,999999999% are the mosfets in this super cheap "inverters"....as always. its boring to watch ^^ fault finding takes 30sec ^^
Yes, but for experts like you! To the beginners of my likes it is priceless, and the channel is not strictly for veterans/experts only 🎉

These video overlays are really distracting. Isn't there a way to delay them till the end? TH-cam is so horrible now.
good morning.
did you mean subtitles
or links in the top-right corner.
please let me know, i will solve it
i mean the iCards, which are displayed on video screen in top right corner.
or you mean the advertisement overlays?
@@HaseebElectronics Not links in the top right corner, the video overlay of previous/additional videos that usually go at the end of a video are now being displayed during the video. They cover almost the entire screen. This time there were four of them and I can't see what's going on. I'm not complaining about your videos, it's TH-cam in general doing these things...always making changes nobody wants :)
@@HaseebElectronics They're called iCards? Yes, they are sometimes intrusive when trying to see a particular test or measurement. Not a problem in all cases but very distracting in some :)
@@jaym5938 sure. i will manage it in upcoming videos.
i am thanful for your valuable suggestion
thank you very much sir...
