Very informative video sir ...its very very short 30 minutes with you teacher جزاك الله عنا خير الجزاء على معلوماتك القيمة وجعله في ميزان حسناتكم استاذنا أشرف ❤❤❤❤❤❤❤🎉🎉🎉🎉🎉
It's great, for you've explained a rather complex system the easiest way possible. I hope in future you'll do some dedicated episodes on three phase drive systems. Thanks!
Great work. You've described 12-step commutation, which is mostly done in FOC mode of control, i.e if at least 2 phase currents are measured in scheme, but, more often it's just 6-step block commutated sensorless drive based on zero crossing detection of Back EMF from motor. ..and by the way, if fore mentioned resistor is damaged there's great probability that an MCU is also damaged..so almost impossible for most people to repair (exception would be an authorized service which has replacement MCU and it's firmware and loader).
it is 6 signal combination to create 3 phase. this SMD resistor damages most of time, if IPM damages, in some cases the reverse flow causes to damage IPM, and most of the times these resistors protect the MCU
Thank you.Very useful basic knowledge in trying to understand inverter drives for compressors and fans in HVAC field even rhough I have limited electronics knowledge
Sir your video content is excellent 👌 with your nicely presentation. Sir I requesting you to make a video on BLDC motor with gate drive timing signal. Thank a lot 🙏
Sir apki videos ko mey dekhta hoon kafi information milti hai lekan sir please koch video urdu mey b bana diya karey smaj ne mey asani ho gi muj jaise insan ko😅 please
Really cool video (as always)! Do the windings in the motor convert the square wave outputs of the IGBTs into sine waves? I hope someday you show a video of this in the circuit with the outdoor compressor unit while it's running and a scope hooked up. If you ever work on one of them. I don't know how practical a video would be with the distance of the board and condenser unit being too far apart, to cumbersome to set up, too dangerous or simply too noisy to make a practical video, but I'd like to see all of this in action. Awesome series anyway! Thanks for taking the time to explain this in such great detail.
Assalamu Alaikum Wa Rahmatullahi is there are have encoder section if there have if you will discuss about this then it will be helpful for us I guess you are always busy but I want to learn something from you cause your teaching method is really so good and if you already discussed please mention the video link here I am requesting you
Hasib bhai aap inverter vfd me c.t section ko explain kar sakte ho how to identify c.t section ok or not... Voltage level par kitne tak reading aaye to sahi mane full explan
You didn't show the freewheeling diodes in the diagram. They are needed for the transient process when current passes from one transistor to another. Or are such diodes not needed?
You are right In this session i just explained the dc high voltage conversion into ac voltage In upcoming session i will explain ipm in detail with all its inputs, outputs, and safeties That diode are compulsory
Sir, Basically i am a technician. This video is specially help me alot to learn. Sir i have doubt from longtime, which is. Ac single phase rectify in dc voltage, then it will entering into IPM. So as you said in video the six low/high IGBT's are doing the work to produce the magnetic. So here the dc voltage only entering into compressor. Somebody say that IPM convert the DC backinto AC. Is this this true? If yes how its possible. Please give me some solution sir. Thank you.

This is so helpful , thank you very much
You're very welcome!
Awesome. Thank you sir. Please explain fo pin and cin pin in IPM.
it is my pleasure
Very good video, you helped me a lot to understand how it works
best regards
it is my pleasure
thanks, its first to understand what going on in timing diagram of 3-phase, i have electronics background but it was not offer in the course!
What an excellent video
Thanks for sharing
الله ينور عليك يا احلى هندسه

Plz explain bootstrap capacitor working feedback ko driver....
And make a separate videos full explanation about ipm
Asslamalkuam... Bhai Mashallah good information Video keep 🆙✌🥀🌹🪴🌻
Grazie 🙏👍
Super objasnione wiedza na wysokim poziomie,czy wie Pan gdzie moge zakupic sterownik do sprezarki aby mozna było podłaczyc na krótko? Pozdrawiam

Dear Sirs, I have a problem with my refrigerator inverter, blinking 9 times. Can you explain about Jiaxipera inverter circuit?
👏👏👏
Hello brother,
I am askar ali from Bangladesh.
Do you have any training center for student?
no i don't have any training center

Is it was the video brother can I know where are you from I thought you are from India
@@MdIsmail-ci5uy yes bro. Am from India and you?
@@rajkhumar001 I was guess you're from India (I am from Bangladesh 🇧🇩)
Trank
😂 super good thanks
Assalamualaikum Bro, what is the form of signals produced by the microcontroller for the IPM, it is a sine waves of square waves? Thanks
it provides square wave signals
either PWM signal or SPWM signals
@@HaseebElectronics Thanks Bro
Hello, is there any way to find pcb circuit schematics? I need to find my IPM number. It has been erased PCB-HTSD008-160705A-PC-V05
Ac Pcb ki diagram kha mille gi
what is the bnifit of this changes?
is the compressor 3 phase?
yes it receives UVW 3 phase signal
Urdu cha
yes brother. i will share it very soon
Thank you Sir
