2nd case when we off. Chopper 1 .stoll ch 4 is on than current flows. From diode D2 as it is forward . But why current is not flowing in D1 from their because d1 is also forward 🙄🙄🙄. Can anyone help 🙄
Thanks for the clear explanation. I have a question though: I think in the video it is assumed Vin is at a higher voltage than motor, so quadrant 1 and 3 are operating as buck mode, and quadrant 2 and 4 are in boost model. Is it possible for quadrant 1 and 3 to be boost while 2 and 4 to be buck mode with this topology?
By applying negative feedback transistor can reversed and it will being acting as opposite logarithmic current to voltage converter , now it will adjust the output base emitter voltage , so for reliability negative feedback use. WITH REGARDS LEARN AND GROW THANK YOU.
IGBT,UPS,UJT,GTO,MOSFET,fet , power MOSFET present on our channel AND I think a.c. dc motor also present Another topics we will work on them. Thank you With regards LEARN AND GROW
During ch1 on current flow from source ch1 and inductor that time inductor store energy and when ch4 come on conducting condition that time no any current flow from source so inductor start discharge . Thank you With regard Learn and grow
I have no idea what you're saying but it's still clearer than anything I've seen from English teachers. Thank you. This was helpful.
Mam u r really great, your teaching techniques is very 👍
Thanks for your words and glad to help you
Nice video and clear explination......well done well understood....u helped me alot for my exam..thanksss
Thanks for your words of encouragement.
It is very clear
Thanks
Very good explained..thanks..
Glad to help you
@@LEARNANDGROW I have watched your other videos,, it will help me a lot in comming PE exams ... thanking you again mam..
thanks ma,am,crystal clear how the 4 quadrant works in a d.c motor
Thanks a lot mam...Really helpful
Glad to help you
Very nicely described.....
Thanks and glad to help you

superb class
Thanks and glad to help you
In fourth quadrant mode ,when chopper four was in off condition,the current flows in the direction as EA -d3 -vs -d2, i am correct or wrong ?
Great video.

Tysm Mam 👌💐
Glad to help you
Super
Thanks
Very understanding vedieo mam
Thank you
what is the difference between on condition and working condition??
Great video mem
THANK YOU
Mam what about series excited diagram ? 🙄 .
why do we need negative feedback in cuurent mirror explain it plz
By applying negative feedback transistor can reversed and it will being acting as opposite logarithmic current to voltage converter , now it will adjust the output base emitter voltage , so for reliability negative feedback use.

mam can u please provide ....IGBT,UPS,UJT,,GTO,MOSFET,SPEED CONTROL OF AC DC MOTOR ,STATIC CIRCUIT BREAKER S,STATIC VAR,HVDC TRANSMISSION LINE
IGBT,UPS,UJT,GTO,MOSFET,fet , power MOSFET present on our channel AND
I think a.c. dc motor also present
Another topics we will work on them.

in FMM why ch4 and d2 are conducting is inductor
discharge energy
During ch1 on current flow from source ch1 and inductor that time inductor store energy and when ch4 come on conducting condition that time no any current flow from source so inductor start discharge .
Thank you
