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.

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.

Nahi,ye speed reference hota hai

Sir how carrier frequency is generated inside a drive
@aforautomation
@aforautomation 3 года назад
there is a separate Oscillator circuit to generate carrier signal.

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
@aforautomation 3 года назад
Now mostly we use Space vector PWM for ac motors.
@parveensinghania8809
@parveensinghania8809 4 года назад
Sr can we connect in condensacant lamp to the output of vfd
@aforautomation
@aforautomation 4 года назад
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..

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
@aforautomation 3 года назад
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
@dhiraj-shukla 3 года назад
Is there any formula to get ac output voltage from inverter?
@aforautomation
@aforautomation 3 года назад
DCV=1.41*VAC
@dhiraj-shukla
@dhiraj-shukla 3 года назад
Sir, This is formula for rectifier output voltage. But here I m searching formula for inverter output voltage.
