[@sagarlamba6753]

Nice explanation😊

[@aniketmore7935]

good and excelllent video but sir vfd industrial use is multiple vfds what reasons

[@naveensingh2519]

Bro we can also change sine wave to desired frequency ..by using cycloconverter as cycloconverter is AC to AC converter at different output frequency....now so why we can't use cycloconverter instead of rectifier and inverter in a drive ?

[@pranavsamant1715]

Thanks sir very helpful

Sir , while stopping IM , we know three breaking methods and as I have a doubt in some applications we use DBR and in some we don't ? and breaking methods changes as per application in drives ?

but i have a question.sir told that,what all changes required that can be done in DC waveform.How this changes are done in DC waveform in order to change the RPM?

[@kranthikumar9685]

Bro, please make a video on power saving in industries .

[@electricalwithabhishekjoshi]

Kranthi, for power consumption one need to do analysis of running load and the requirements of plant. There are not much things to say without doing analysis of System.

[@harishrawat3557]

Thanks sir mai elevator lain mai hu

[@rajuvasava1736]

Sir imcc pe video banaye

[@AbhishekPandey-yy4zi]

sir ac-dc-dc choke -inverter and output voltage

[@naveensingh2519]

Bro we convert in dc only because we have to change the frequency and for changing the frequency we require inverter and inverter requires dc input that's why we change ac to dc first then if feed to inverter and by varing firing angle we change output voltage and frequency to control speed

[@bch2780]

The topology circuit that use mostly nowadays is voltage source that convert AC to DC capacitors then use inverter firing PWM patterns to vary u/f

[@ayushtechnocareatc7820]

Capacitor bank,and IGBT CONCEPT IN VFD

[@shamsheralam9572]

VFD me fault kon kon sa hota, reverse speed motor kiun sirf chalta hai

[@tharunjangam8228]

Please explain more briefly regarding why we have to convert ac to dc other than waveform

[@bch2780]

There are many power electronics topology for VFD, Voltage source apply ac to dc store to dc capacitors then inverter to motor

[@endlessLove591]

sir vfd kaise select karte hai iska rating kya hai kitne amper leta hai

[@adnanali6020]

Hello sir inverter vfd Kya hai is k bare me please kuch batain

[@growelectrical2900]

Can Dc motor not run with help of vfd?

[@electricalwithabhishekjoshi]

VFD is only for AC motors.

[@riteshpatil1264]

Why the motor not get burn in case of VFD as frequency is zero at starting? Induction motor is acts as a transformer and if frequency is zero at starting.

[@rashikatirpude1928]

Sir vfd with star delta starter explain kariye na

[@SahajaRythuWoodpressOils]

[@pullastiswain7286]

Sir my question is VFD ka input and output current same kyun nahin hota he or kya reason he

[@santoshwagh4742]

VFD me DBR dynamic breaking resistor kyu use karte hai

[@uzairali6875]

please make a video on "why braking resistor is used in vfd?"

[@bch2780]

Some application, need to reduce speed motor more faster than natural mechanic inertia, during reducing motor action like generator convert mechanic energy back to the heat at braking resistor

[@bhupeshkirve1216]

Advanced level interview video shear sir plz

[@aswingopal8617]

Can you please make a video explaining the parameters of a circuit breaker(breaking and making capacity, max fault kA rating) for a ABB or Schneider breaker and how it is calculated.

Sir vfd me parameter kese set karenge.

[@Scheme_Match]

Sir what is difference between u/f and vvc Motor Control principle ..please make video on this

[@bch2780]

U/f only control and keep ratio u/f, vvc have to control flux component and torque component separately
