TnQ so much for your teachings Sir(Every topic for me is going so easily now). Alt for Q/2 (video 3:59) ----››› · Switch will conduct when diode will be in OFF position. So, T(ON) = 0.1 - 0. 05 = 0. 05 T(total) = 0. 1 D(Duty cycle) = T(ON)/T = 0. 5 so, Delta IL = D(1-D)(Vs)/fL [f=1/T ; Vs = 100V ; L=1mH] =2. 5
fabulous sir kya padhaya hai aapne jabardast... sirrr mai lgf ke pure tutorial ko follow kr raha hn ase hi aap padhate rahe to next time gate crack kr hi lunga.... god bless u sir for ur work....
thanx for the compliment shoeb..just watch each and every lecture...at the end you wont get problem in solving power electronics question..also share with you juniors about this channel..all the best for gate 18...
Sir thnk u so much Earlier I had a lot of confusion and doubts about the topic but now i am able to solve any questions . Credit goes to u sir ..... Sir its humble reques plz Upload videos explaining the concept of dc drives and ac drives part of ese syllabus .we r facing a lot of problems....
Sir just fabulous. Thank you so much sir🙏 And really thank you so much for free Coaching.. I can't say how much it's useful for few persons who cannot afford to pay for Coaching.. ur doing great job sir.. God bless you sir.
sir in que 2 there is ans is same but there is some mistake i think...bcz the waveform of diode conduction is given..not the waveform of output voltage..so ans remains same bcz of same duty cycle
thnqq so much sir for teaching us in such a creative manner!! Can u pls tell when wud u upload the lecture for power system..and if not then wat should we follow??
Till now, in the previous questions___ only one source is present. So, Switching represents T(ON) & T(OFF) So, D = _____ value exists But, in this question, Switching means changing from 10V source to 5V source. So, during OFF period Source-2 is coming. So, it is conducting continuously. Then, you can take D as =1
ha ho jayega..machine 2 pehle cover karunga..kyu ki iska video lec kahi par sahi se available nahi hai..and i will try to cover this..ok...for transformer and dc machine..refer nptel video lecture..jaha se mai padha hu..its nyc..link is given below.. sohailansaari.wordpress.com/nptel-handwritten-notes/

awesome lecture, took less then 30 mins to practice previous year question from this and previous lecture, thanks sir
ur most welcome..just watch each and every lecture..u wont get prblm in real gate exam..all the best..
LearnGATE Free sure sir..

· Switch will conduct when diode will be in OFF position.
So, T(ON) = 0.1 - 0. 05 = 0. 05
T(total) = 0. 1
D(Duty cycle) = T(ON)/T = 0. 5
so, Delta IL = D(1-D)(Vs)/fL [f=1/T ; Vs = 100V ; L=1mH]
=2. 5
Duty cycle is always with respect to switch, where Ton is first half cycle of conduction not the second half cycle
Thank you very much Sir!!! Your teaching is extraordinary. Every student can understand the way you teach.!
Thank you sir for ur Noble effort for making lectures on PE

9:11 why do you not consider Vl the voltage across the inductor ? Why is their no voltage drop across the inductor ?
sir in que 2 there is ans is same but there is some mistake i think...bcz the waveform of diode conduction is given..not the waveform of output voltage..so ans remains same bcz of same duty cycle
Thanks a lot sir.....
thnqq so much sir for teaching us in such a creative manner!!
Can u pls tell when wud u upload the lecture for power system..and if not then wat should we follow??
follow nptel lecture by prof. ak sinha from iit kgp
Thank u so much sir
In Q2, the waveform of Vd is given, V• and Vd are two different things... Since duty cycle is 0.5, so no effect on the ans...
Pls correct me, if I am wrong... ???
Sir why u neglect the vtg drop across the inductor in pblm 4?
DEAR SIR
WHEN WE WILL BE ABLE TO SEE THE INVERTER VIDEO
INVERTER IS TO IMP. FOR EE STUDENT PLZ. UPLOAD THAT VIDEO SIR PLZ.
sir in lecture 23(b) in Question-4 why u have not taken Vo=DVs to calculate the output voltage across R by both the source??
@Er.S Bibiyan Yeah I have also done by this method only but I didn't get solution by Sir. How can we ignore voltage across inductor?
Sir please upload the inverter section.
sir in question 4 V0 should be DVs, why didnt you consider D sir...please reply
take a screenshot and upload in our facebook group

ur most welcome..
🙏💕🎉🎊👍
How VLoff= - Vo ??
sir power system aur machine ka lacture kab ayga aur sir apka koi contact no. hai(please reply )
time to lag jayega...kuchh keh nahi sakte..mere personal schdule par depend karta hai..
phir bhi sir after 3 month
october tak jaha tak hoga waha tak kar dunga..promise nahi kar sakta as i m getting married in last week of october..hope you understand..
sir to October tk se phle machine start ho jayega
ha ho jayega..machine 2 pehle cover karunga..kyu ki iska video lec kahi par sahi se available nahi hai..and i will try to cover this..ok...for transformer and dc machine..refer nptel video lecture..jaha se mai padha hu..its nyc..link is given below..

Sir, in problem 4: When 10V is acting, the ckt acts as step down chopper, then Vo=DVs =4V. When 5V is acting,Vo= DVs =3 V. On finding avg, Vo= 3.4V
there is no free-willing action here. So Vi=! DVo
