This is very useful information for student. Please make more videos on power electronics

[nikhilsarode]

Please make video on designing of cuk converter. And also on how to select a appropriate switching frequency for dc-dc converter.

I think the last calculation where RoB is calculated is wrong because Io average is not equal to the average inductor current. io average = iL average * (1-D) so the RoB should be 12/(1.5*0.67)=12 ohm

the introduction at the beginning of the video makes me feel like watching Marvel movie Lol

[juliamoranchomarzal]

Thanks for the video, it helped alot.

[democracyforall]

how do you switch on and off the mosfet or igbt

[muhammadfaizannisar]

exceptionally phenominal plz made more videos

Thank you for the explanation. Why are you using +12 instead of -12 V for Vo? and if it's negative, shouldn't it be: Vo/Vin = - (D/1-D) ? Thank you!

Please make a video on Non-Inverting Buck-Boost Converter and Fly-back Converter asap. Thank You

[mikelemon]

Does this university offers more extensive power electronics courses else where?

Hello Sir,
Can you please provide the explanation for taking the value of Integral control as 4 times the switching frequency .
Thank you Sir.

Hello Sir, i simulate buck-boost converter that connects to pv array and mppt at matlab. But the result i get is, for iC off = iL + io. So i get confused, which one is right? iC off = iL + io or = iL - io? Thank you Sir

[muhammadfaisalmalik]

but when the load is non resistive load but an DC shunt motor the output polarity is reversed as shown in the video it means the motor rotation will be in reverse too?

[aspboss]

Wow, the most fruitful video on the internet.. .
