Really you have make all our concepts clear, thank you Sir

[@tejayadav6808]

Your teaching skills extraordinary sir Please do as possible electrical subjects

[@sumansarkar3069]

very help full... thank u very much for all the lectures

[@Er.lokesh]

Thank u sir,........sir please upload amplifier video.... and previous yr. analog questions.....

[@vishnukt8633]

great work sir,thanks a lot

[@apostolosmavropoulos177]

dear sir , why do they have thyristor sign in problem (4) 2004 instead of switch?? i thought that thyristor is unipolar and we can only controll turn on state of the thyristor..am i wrong?

[@bappabain2142]

thank you so much

[@meeragupta3571]

thanku very much sir!!

[@dineshnikam736]

very helpfull ........thanks

ur most welcome..

[@NARESHNARESH-go6fp]

Questions 3
Sir can you pls explain y you taken output voltage is equal to supply voltage

[@valarmathi9156]

thank you

[@SundasLatif]

Helpful

[@ravendrayadav6540]

thank youu very much sir

[@avirupkar935]

In problem no 3 why did you consider T=1 ms not 200us , we should have considered 200 us as we are dealing with on condition

[@AakashSuryawanshi]

True

[@kms7616]

T is always 1ms and in on period DT=200us

[@jblife123]

Pls help.
A buck converter is supplying 360W to a 10ohm resistor. The input voltage is 100V. Assume all components are ideal and converter is operating in continuous conduction mode . Find the average inductor current

sir can u please clarify that we shud wait for inverter lecture or not ,it will be very helpful ,as mind is so used to ur lecture ,and few topics bit tough.so, need ur easy way out.

[@nilutpalsarma1178]

Thank u sir

[@rubultalukdar3861]

Sir, at problem no. 3 how will we identify that it is a buck converter??? No hints are given

[@apurvatyagi8198]

Sir ques m kse pta chlega k buck converter h ya boost.. plz clear the doubt

[@joyebkapadia2650]

Thanks :-) Does they ask questions based on four quadrant operation of choppers?

[@GATEMATICEducation]

u can study but i dont think quesiton will come..so i have not included in my lecture..

[@joyebkapadia2650]

LearnGATE Free thank you and waiting for inverter lecture.

[@buddulapravalika2460]

Sir suggest me for engineering mathematics gate preparation

[@borhanahmad8399]

How to calculate chopper efficency

[@ATULSINGH-ki1el]

sir 2018 boost converter ka solution samjh nhi arha plz soln. upload kriye

[@srikanthpalem9373]

Sir u haven't included gate2000 question in this lecture
