Thank you somuch Narayanan sir....... I am totally unaware about power electronics... But after watching this video, its totally clear about the concept .... Nice informative and clear in depth ..
Hello, Great lecture! Thanks for sharing! I have a question regarding common ground. I'm rectifying 110VAC and then inverting it using 4 IGBT and 2 IR2101 MOSFET Drivers. I'm also using an Arduino Micro to control the frequency. Should I connect the ground of the rectified 110V to the ground of the Arduino and Drivers power source?
Thank you professor for this excellent explanation of the power part. But how can we control the gates of IGBT or Mosfets with wired logic? My problem is that I don't know what is the reference potential to choose for this logic since we have to apply to the gate of each transistor a voltage of 5Volts or more. If we take as reference -Vdc it is easy to control the gates of the IGBTs connected to -Vc, but how to proceed for those connected to +Vc? Thank you in advance for a possible clarification.
Insightful lecture Dr. Narayanan, Thanks. Looking forward for more practical implementation examples, for example, the waveform is always square in this circuit how do you get a sinusoidal waveform? Thanks a lot anyways.
+Giridhar Raju N M He mentioned that in order to get a smoother curve with less ripples, the Pulse Width of the multiple notches should be varied that will result in a more sinusoidal kind of a waveform. Also, the voltage level can be modified using the same. This method is also more widely known as the Pulse Width Modulation (PWM) Technique. Hope this helps!
Subtitles that u have added interrupt all the time while understanding the figure please don't keep it otherwise keep it such that we could see the figure
From 46:23 it's totally nonsense 😂 I have never seen IGBT with diode in series instead of antiparallel.... Don't get offended.... I already working with 3 phase IGBT BASED BOOST RECTIFIERS AND INVERTERS , AND GOD KNOW WHEN WE WILL ABLE TO BRING TECHNOLOGY TO SOCIETY USING THIS TYPE OF TEACHING SCHEMES IN ENGINEERING COLLEGES

this the best lectures among all on youtube
good lecture. it will be great if you can filter the noise
Very informative and clear .Thank you Sir
My life changing lecture
thank you sir for your lecture and thank you NPTEL
It's really a wonderful lecture. Thank you Sir
Nice, good clarity given by Ur lecture thank you sir
Thank you sir. It is worth attending.
don't get why we need the antiparallel diodes when switches on the other side can change the current flow direction
Excellent Explanation.

always Best !! Thanks Professor!

i have enjoyed mostly sir

Thanks karan,
That helps.
Nice lectures sir
why do we need bidirectional switch?
Hello, can I get a video for the ac to dc conveter
Nice video
Why capacitor is connected across the load?
To reduce voltage ripples, a large cap will provide an almost constant voltage to the load which is preferred.
To make the output smoother.
Thank you .... sir...for given this lecture
👍
Good!

The thought (bring technology to society) u have is grt...
U can take initiative to share your knowledge to the students ..
Poor Person with little knowledge claiming to be converter designer is judging professors of IISc 😆😆😆
This is current source inverter. You are saying it for voltage source inverter where the anti parallel diode is used.
