Dear Mr Haseeb: I am absolutley fascinated with this video series. I have learned so much from you dear sir!!!! I especially learned a lot about the MOSFET driver circuit. I understand that when a IGBT or MOSFET short to the gate that damage to the dirver circuit can and will result, but how you show and explain the failures that can happen and how to troubleshoot them is such an amazing valuable lesson. Again, I cannot thank you enough for all the wonderful videos you have made. Thank you so much for the time you put into these lessons. Know for sure dear teacher that you are helping a lot of people just like me!!!!! All the best to you!!!!
Love your way of working, you work like a pro, there is many noob i saw who dont know the working of pcb or the components they just replacing all parts one by one till the problem resolve 😂 First replace the mosfet if it burn replace the ic, if not work threw it in trash 😂
Wow, that was explained well. I'm about to test MOSFETs on all in one inverter on the battery side. There is no short at battery with meter but battery trips short protection in BMS. Solar and inverter sides work fine.
this video answer my question why mosfet fail, i though because i bought from Aliexpress. thank you brother always your video informative and brilliant
Thank you so much 😀 welcome bhai you can check my second channel "haseeb electronics urdu" that is in Urdu language, it is just for my pakistani & indian brothers
❤ I love you sir ❤ I am praising by the name of allah Alhamdulillah. Sir, really, i have learned to you so much knowledge. by watching your online teaching method, feel free to do dua ''jajakallah khair'' mashallah 🇧🇩 sir I am from Bangladesh.
fantastic video! ... I think your lessons are too important so I think you deserve to see a second camera detail !!! ... Thanks for sharing knowledge sorry for my English greetings from Spain
asslam o alaikum i was very happy to see your video chking with osciloscope. it is interesting so now plz make video osciloscope check circuit in urdu. thanks
Hi friend how are you. If I don't have an oscilloscope. Can I use an headset to listen to the signal. Please whow aproximtly the voltage of the signal and its frequency.
Looking of the connection you have made sir to the last transistors which are npn transistors. Emitter of a npn is connect to a base of pnp transistors .my question is are we going to connect emitter to ground from each transistors( npn ) and base the output of the ic.there are two legs of a transistors which are not connect. E.g.. collectors and based of npn transistors.
Hi Haseeb. Maybe you can help. When fixing the inverter I remove 4 transistors, 2 PNP and 2NPN, but I forgot to mark or colour code it and now I don't know which way is the correct. From the other side it looks that the emiiter of each pair of transistor goes to gates of the mosfets. The orientation of the transistor is marked on the board but not which pair is NPN or PNP. Any way to find out? there are 2 C945 and 2 A733. There are 16 Mosfets in my booster stage. Thanks
exactly, two mosfet from one transformer and two from second transformer will work together that means four mosfets will work together while the other four will remain off. in upcoming video we will install mosfets and will see their operation sequence using oscilloscope
My friend.I have a Grid tie inverter 600Watt power.It does not have LIMITER SENSOR.So times come and feeds back the grid.Is there any electronic small motherboard that will help to create an additional limiter sensor arrangement.of course i have the clamp sensor.Thank you.
Salam Aleikum, can we check the mosfet on circuit ? how to test the IC that manages the 4 mosfets in the H Bridge. My inverter produces only 140 Vdc then shuts down because of protection. I also takes more than 3A from my 12v battery to eventually produce only 68vac before shutting down. All mosfets and their gate resistance in the 12V section are good, measured on circuit. Thanks for your guidance to find the short.
Aoa . Sir. After rectification of faulty components. Still one side chopper fet's get heat up but when i remove one any one chopper s FETs its works correctly bt the output voltage drops to 130 volt s due to one side chopper What can i do ?
Thank you so much for this great videos, Im trying to repair kind of electronic devices like this, so can you suggest me an oscillospe, which are price-performance device, for this kind of works, Allah(c.c) bless you.
best regards dear if you can find some 100MHz, dual channal, 1GS/Sec (1 gega samples / second) that will awesome you can also 50 MHz but i will recommend 100MHz, try to find Hantek, Regol, Uni-T brands or similar if you want to ourchase online, try to explore Banggood online shopping china
Hi, 3000 watt full sinus inverter fault light is on. When the inverter is turned on, a relay tripping sound is heard, then the fault light is on, what do you think could be the problem?
yes it is possible but it becomes very very long so that is reason i am sharing in parts part 1 - video number 439 part 2 - video number 442 part 3 - video number 443 this part 4 - video number 446 next parts are coming soon
thanks for your response I have seen all these videos You have explained very fluently and well Without complicating the circuit thanks a lot I am waiting for your next video
What could cause 1 mosfet of a parallel set to be damaged continually, when only 1 mosfet is installed per drive,, The circuit works properly. The gate drives test good when no mosfets installed.thanks for any help you can give me.
What is the reason for turning power on after scope probe is placed in contact first instead of turning on power and then placing probe? How much voltage was being applied?
because MOSFETs are not installed in the circuit, and if we turn ON the inverter and then we connect scope, in this connection time the MCU will disable the TL494 because the MCU will fail to find output voltage. it waits just few seconds for availability of the output. in next video i will install mosfets and then we will check all signals without turning ON/OFF it is applied 12VDC and there was no output so TL494 was operating at maximum duty cycle. when the mosfet will present the inverter will produce output then the duty cycle will decrease automatically
yes dear in modern electronics technology it is necessary to use oscilloscope. because it needs to view the signal waveshape, otherwise it becomes difficult to locate the fault

one primary side of transformer has driven by four mosfet switch. is it each four mosfet has opposite to each other simultaneously
exactly, two mosfet from one transformer and two from second transformer will work together that means four mosfets will work together while the other four will remain off.
in upcoming video we will install mosfets and will see their operation sequence using oscilloscope
Please tell me , kya 12v to 220v inverter ferrite transformer mai ferrite core mai air gap honi chahiye ya nahi..?
Haseeb bhai Namaskaar 🙏.
How can I test the proper gate drive to for
mosfets with the help of a multi meter.
Please reply. Thank you 🙏

Pls which transistor is equivalent with hy2d pls
HY2D is SS8550 pnp transistor
you can use any 40V 1.5 ampere PNP transistor
or use
2SA2056 WF SOT-23
Y2, BF coded PNP transistors
Hi you promised to explain control in 3000inverter series we are waiting
Sir g lm2903 ki jaga lm393 laga sakte hain ac dc inverter out door bcb main please rehnomai krn
yes we can use it
these are the same
@@HaseebElectronics Thank you sir
Why two transistors PNP and npn connected in that way also why resistor and diode connected in parallel before reaching the mosfet gate resistor
If the tl494 is bad will it burn the MOSFET also
Please what device did you use to power the the inverter?
i have power DC supply
@@HaseebElectronics can any DC power supply power it? Like 30v 5A?
Why did you change your oscilloscope from Hantek to Rigol?
Hantek is in my office. and i purchased New RIGOL for my home
these days i am staying at my residence due to some health reasons
Sir,
Whether this checking method is possible by Digital meter without oscilloscope. If possible please give a vedio.it is most important me.
Aoa .
Sir. After rectification of faulty components.
Still one side chopper fet's get heat up but when i remove one any one chopper s FETs its works correctly bt the output voltage drops to 130 volt s due to one side chopper
What can i do ?
how sir what is the function of those four capacitors?
Thank you so much for this great videos, Im trying to repair kind of electronic devices like this, so can you suggest me an oscillospe, which are price-performance device, for this kind of works, Allah(c.c) bless you.
best regards dear
if you can find some 100MHz, dual channal, 1GS/Sec (1 gega samples / second) that will awesome
you can also 50 MHz but i will recommend 100MHz,
try to find Hantek, Regol, Uni-T brands or similar

Hi, 3000 watt full sinus inverter fault light is on. When the inverter is turned on, a relay tripping sound is heard, then the fault light is on, what do you think could be the problem?
Thanks for your tutorial
Is it possible to analyze the complete circuit of this inverter? Thank you
yes it is possible
but it becomes very very long
so that is reason i am sharing in parts
part 1 - video number 439
part 2 - video number 442
part 3 - video number 443
this part 4 - video number 446
next parts are coming soon

it is my pleasure
Sir, inverter driver check karne k liye oscilloscope ka full setting bataiye, please.....
Sir is it necessary to have an oscilloscope for checking signal
yes dear in modern electronics technology it is necessary to use oscilloscope. because it needs to view the signal waveshape, otherwise it becomes difficult to locate the fault
Very nice,
Thanks sir
Its available in hindi? Please give link.
this is not available in urdu, i will make a video and will share it oon
Just concern with cap which make oscilloscope higher enough
yes dear, we will check capacitor and its voltage
