Wow maja aa gaya, nice explanation 👏🏻👏🏻

[@satyabro6788]

Bahut achha sir❤❤❤❤

Ek no sir..Naya method pwm ke bare mai kuch bataye sir

[@umargul5644]

Great job thanks sir very useful thanks

[@nandinikumari7632]

Sir really it's very helpful video sir, the way u explain is wonderful sir

[@amitkumardewangan848]

Very nice explained sir 😊🐱🙂

[@ghulamakbar8030]

amazing sir each and everything is well explained,wonderful. carry on sir God bless you,

[@muhammadadnanahmed8324]

Great explain

Please post informatic videos regularly.

Itna achha youtube me koi video nahi pmw k baare me

[@mayurI4188]

Very good explanation sir

[@danielsarker4643]

Thank you ustad, its interesting. I started to listen the subject now. I work as a conventional a/c mechanic but your way of teaching is very good. I shall stay with you as I could in this lock-down time. It will be very helpful for me to upgrade me knowledge, thank you sir. Though I undrestand hindi quite good but as a technician its ok. I am from Dhaka,Bangladesh. May Lord bless you.

[@aforautomation]

Thank you so much.

[@sunnykings439]

Knowledgeable tutorial.

[@sureshpadhy2243]

Excellent

[@rashmiranjannayak3251]

Achha Batayehe Appko Ases Dhanyabad, Now a days micro processer is used to generate the 0-5 v pwm pulses with analog output for same and then a mosfet driver is fed to this value for higher current.

[@aforautomation]

Thankyou so much sir ji.

Sir servo drive ka output jo motor me jata hai vo bhi pwm hi hota hai ??? ,, please explain hoe servo motor stop at perfect angle.

Sr can we connect in condensacant lamp to the output of vfd

[@aforautomation]

Yes lamp can be connected but as VFD output is PWM and lamp is not an inductive load it will not glow properly.connect 3 lamps in star connection..

[@parveensinghania8809]

@@aforautomation Recently i did this for 5.5 kw vfd but drive Got flashed

[@debduttbhattachargee1814]

Reference signal actually Input supply Voltage hota hai kya Drive ka?

[@aforautomation]

Nahi,ye speed reference hota hai

[@mintupal5616]

As u said in the last that this is a oldest method for pwm, so what is new technology now a days vfds are used

[@aforautomation]

Now mostly we use Space vector PWM for ac motors.

[@sunilpandey9972]

And other motor control method

[@rajeshkumarlenka3177]

Sir how carrier frequency is generated inside a drive

[@aforautomation]

there is a separate Oscillator circuit to generate carrier signal.

[@AmitKumar-ge7lj]

Sir B&R drive k alarm k bare m btye

[@dhiraj-shukla]

Sir, What will be the formula to get three phase pwm inverter output voltage? In this video it is showing DC voltage will be the output means 580v.but we get 415v ac in output.how it come?

[@aforautomation]

580 volt dc is equivalent to 415 v ac. if you check DC voltage you will find 580 volt,on 50hz output frequency.

[@dhiraj-shukla]

Is there any formula to get ac output voltage from inverter?

[@aforautomation]

DCV=1.41*VAC

[@dhiraj-shukla]

Sir, This is formula for rectifier output voltage. But here I m searching formula for inverter output voltage.

[@sandeepgautam5168]

Theek hai

[@shaileshnandansihha854]

Nice vedio but VFD smps par vedio banye

[@aforautomation]

thanks,, Smps you mean to say power supply which is used for control voltage in VFD?
