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 ?
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 ?
IGBT SCR are the semiconductors component of Frequency drive, Maybe we can classify the type of frequency drive are Scalar,Vector,DTC control, or Voltage source,Current source inverter
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.
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?
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.

Beautifully explained 🇮🇳✌🏻
Can u make more question on vfd plz for interview.
Very informative...🙏🙏🙏
Thank you..
The way you explain things is just brilliant.
Kya VFD ko electric bike me controller ki jagah pe use kar sakte Hai?
Sir vfd ka use karke ham motor ki rated rpm se jyada rpm badha sakte hai kya
Kya VFD ka input supply change kare to motor ka direction change hoga
बहुत ही अच्छा सर ।
Very nice explanation.
Please explain differences between vfds and softstarters. Also explain reasons for selections of vfds and softstarters.
Very nice explanation
If you process need to vary speed of motor, use VFD.
Which type of changes we have to done when current is DC type so we have to get variable RPM or explain the method by which we have to vary frequency
Due to high harmonics in our plant VFD and Motor got damage can you suggest any equipment to reduce the harmonic
kon si waveform ko modify karte hai current,voltage,frequency
Ap badhiya samjate hi sir ji
Great my important dout is clear thank u so much.
Bhai kia Vfd invetar lagany sy ham ect bill kame kar sakty h.yane bajle ke saving ho sakte h plz
Thanks sir interview question ka lea
Most welcome Rishikesh.

Sir kia hum rpm 1500 say ziada bhe kar sakta han ? Thanks
Sarfraz, hum motor ka RPM, rated RPM se jyada nahi kar sakte.
@@electricalwithabhishekjoshi Thank you sir, from PK
Most welcome Sarfraz.
Yes karsakte h lekin motor na generator ki taraha Kam krne pages with negative slip
Nahi
VFD me DBR dynamic breaking resistor kyu use karte hai
good and excelllent video but sir vfd industrial use is multiple vfds what reasons
Good information
Can Dc motor not run with help of vfd?
VFD is only for AC motors.
Please add some more questions about VVFD

Sir whate is a vsd
Sir aap kon se plant me hai abhi job aap ki
Why motor produces humming sound while using VFD
And
If possible please explain about
Internal parts of a VFD like dc choke and filter etc etc
Okay Saikumar..
Single phasing hua hoga
High switching frequency trig IGBT is the cause of sound
Sir vfd me parameter kese set karenge.
Sir old and new VFD me kya fark hai
Hello sir inverter vfd Kya hai is k bare me please kuch batain
Sir here we vary the frequency but in DC frequency is zero how we change the frequency in 1500 to 1200 in dc
You’re video is very helpful
Thank you Nikola.
@@electricalwithabhishekjoshi sir what is difference between sensitive earth fault and earth fault
Great sir... make video on PLC automation also
sir vfd me HD & ND kya hota hai
Sir VFD OUT PUT NAHI AA RAHA
Why freewheeling diode use in VFD plz explain..
Use for the energy path feedback to dc link while motor reduce speed, General IGBT always have freewheeling diode integrated
Sir please explain about IGBT and test
Sir how many types of Frequency drive are there like igbt ,scr ..pl explain on it
IGBT SCR are the semiconductors component of Frequency drive, Maybe we can classify the type of frequency drive are Scalar,Vector,DTC control, or Voltage source,Current source inverter
Sir Aditya Birla company me kaise a sakte hai electrical engineer

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.
VFD me card kon kon se hota hai
Sir can i run one vfd through two motors running at a time?
Sanjay why you want to run VFD through motor?
We run motor through VFD.
Yes .
Sir , soft starrer & vfd ki comparison per video bneye
Okay Arpit..
Thanks so much for valuable information
Great video sir
Lekin dc mei frequency nhe hoti h na then VFD mei dc karne ka concept kya h.
Sir DC ki frequency to zero hoti fir kaise frequency Change hoga
Very nice explain
Thanks sir very helpful
If frequency is one hz then output voltage in VFD is 16volt why not 415/50=8.3 volt..
Plz explain
Bcz frequency and voltage is not linearly related
At low frequency the u/f is higher , because the function VFD need to compensate voltage drop at stator resistance of motor
Sir, make a video on REACTOR.
Sir Lekin DC wave from ka frequency to zero hota hai to change kaise krte hain???
Good sir sir G main aap ki all videos watch kar na chahta hoin
V/f in inverter ? Explain sir G
Industry VFD Soler per chal jay
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?
D c wave form se ashani se igbt ke gate ko kitna open kar hai yah control karke igbt ke output par a c pwm ki form me mil jata hai
How dc pulce is changed that causes speed change
ABB ACS880 vfd drive please explain with trouble shooting
Sir imcc pe video banaye
ब, vfd केवल कितने तक मे आ जाता है ईसके लिए कितने वाट का पैनल लगेगा
Superb bro
Vfd check kaise karenge usske upar ek video banaiye please..
Not explained how you are changing the rpm with DC straight line. How frequency varies and relation between Voltage and frequency. Please explain
DC is the voltage source of inverter, the PWM firing pattern of inverter make change voltage/frequency
What happens to voltage .
Is the voltage also decreases when frequency is decreased....???
The ratio u/f have to keep constant for constant load application, the ratio u/f is the develop torque of motor
Sir aapne bilkul sahi kaha per me bol Raha hu ki vfd se kitne kw ki motor run kir sakte he
Thanks for useful and knowgable video sharing.
Thank you Sir
VVVFD ka upar complete video banaye sir please
Please explain more briefly regarding why we have to convert ac to dc other than waveform
There are many power electronics topology for VFD, Voltage source apply ac to dc store to dc capacitors then inverter to motor
amazing explanation
Everything is don but I asked sir how increas to motor rpm pleas explane??
Stator voltage frequency change rpm motor
Sir can we use over size VFD to low hp rated ac motor
For u/f scalar control is possible, but for vvc vector control is not accurate enough to calculate torque
Please explain how we get speed regulation by varying 0 to 10v or 4 to 20ma signal reference in VFD
How the frequency changes happening in vfd
What level of your electronics or electrical education
Bro, please make a video on power saving in industries .
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.
Sir vfd with star delta starter explain kariye na
Sir what is difference between u/f and vvc Motor Control principle ..please make video on this
U/f only control and keep ratio u/f, vvc have to control flux component and torque component separately
Nice bro 👌
