Thank you, professor.
Very nyc explanation for LLC ever seen ,🙏👍👍
Thank you for sharing this wonderful knowledge. Sir, please make a video explaining different control topology of LLC resonant converter(i .e. fixed frequency control and variable frequency control). It will be a great help for this community. Thanks once again.
Thank you very much. Its so helpful
That was pretty usefull, thanks a lot!
Great job.
Thanks , that's is great lecture, good mentioned.
Thank you so much.
Thank you Dr. How to know the range of frequency that the converter should work on it, means minimum switching frequency and maximum switching frequency.
thank you sir for latest trending teachnical video
thank you Dr. Could you please send me the code that u used to plot the curves?
Thanks Professor Ahmad,
I wonder what would happen if Instead of H bridge at the input we use just the say 110V or 220V outlet power (which is sine wave 50 or 60Hz) and make the 1/(2*Pi*SQRT((Lr+Lm)*C) equal to 50 or 60HZ (line frequency)? Can you do the calculation?
Also, do you have your calculation in written form?
Thanks alot , is it same for HB LLC?
Could you do a video explaining how to design a Dual Active Bridge (DAB) ?
Are there any controller ICs you would recommend for a full bridge llc
Good work sir , can you please share the Simulink file or atleast the transformer specifications used in Simulink
I have a basic question. Do this circuit only convert voltage unregulated for make the isolation purpose or do this circuit do both isolation and DC control regulation at the secondary side. Do this circuit need a second regulator for control the DC voltage level.
I am designing LLC converter for battery application, can you guide me in the design process?
Transformation ratio is taken as the ratio of DC nominal input voltage to DC output voltage. Can you throw some light on how you fixed this relation.
I would like to thank you for the useful information.
Second, I have some questions that I hope to get clear answers to help me design my circuit:
1-Could I use an LLC Resonant tank with a multilevel inverter Or it is limited to use on half-bridge and full-bridge only. If I use it with a multilevel, does it affect the waveform of the output of the inverter?
2-What is the output voltage waveform of the resonant tank (VLm)? Is it the same as the waveform of the output voltage of the inverter (Vinv) or different?
3- I found your work very close to mine, so I would like to cooperate with you in completing my work if you do not mind, and this is my private email.
Very clear explanation sir. Thank you so much sir. How can I contact you sir.
Sir, please do a simulation video of full bride LLC resonant dc dc converter
Dear sir
I am working in this topic, if you have any matlab file please share to me
@@bhavsinghbhukya6246 hello sir , i am also working in this topic, can u please share the matlab file, with associated research paper
Thanks ! Can we get the Matlab file please ?
What is Re?
When operating at resonant frequency, R=0, so IL goes to infinite values, sorry I didn't understand.
At time 6.13, how 8 / pie sq. came? Can you please elaborate...
I believe 8/π^2 is the product of 4/π and 2/π, where 4/π is the weight of the first harmonic (fundamental frequency) using Fourier analysis and 2/π is the factor for the average of a full-wave rectified signal.
Thanks 🙏👍💯😊
Isn't there a mistake in 7:12 when calculating the magnitude ?
sir, can i get the matlab file.
