VFD !! DC BUS VOLTAGE GREATER THAN INCOMING AC VOLTAGE, WHY ?

VFD !! DC BUS VOLTAGE GREATER THAN INCOMING AC VOLTAGE, WHY ?

[munnalalbharadwaj]

Thank you sir verry nice to explained.

[zeeshanirshad]

not explained properly about dc voltage calculations and what is UDC?? what is value of udc

[amitkumarmukherjee]

DC link voltage is 300v DC - what might be the problem?

[Kumar-udhn]

Good. But how does the drives save the electrical engery if the process parameters need to be kept same. I believe, its only marketing strategy of manufacturers to sell more and more drives. In fan application, it may affect but other applications, , , ???

[miluabraham]

how can we determine the value of choke and dc link capacitor ? any equation to find out that ? please help me out . thanks

[gopalpillai]

There are about 16 protections in ACS drives, can you cover imp ones in one episode, since no such videos are available.
Why it is recommendex to change the DC bus capacitor after 10 yrs.

Sir...I checked vfd incoming current that's value is 10 amps...but when checked vfd outgoing (motor side) then value shows 30 amps...

That means vfd saving power...but my question is...what phenomenon happen in vfd that's reason outgoing current is greater than incoming current.

I have set 440v in drive but as voltage comes to 415 v drive get stop.

[amrishkumar]

Can we use 415 volt dc instead of 600 volt DC in igbt inverter

[jeebannayak]

Sir, how v/f will be constant only varying frequency?

Why do you put an English title to your video while the video is in your language???

Sir agr vfd m power card se dc nhi bn rha to us candiosn m kya kre
