Good video

Try all 4 switches as MOSFET and implement the simulation

We need videos on DAB converter

Make a vido on bidirectional AC/AC converter

Awesome! Thank you very much for your content!

Thank you 👍

It is showing error, at time 0.0 The state 1 in pid controller2 is not finite, So simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances). I tried that remedy but it is not working out

Thanks!

Hi, thanks for the video.
But there is a huge current spike in the input side current. How can we remove that? Please reply.

Hello are u a freelancer?

Hello and thank you for the video.
How do you tune the PI controller parameters please ?

Thanks again

I attempted to replicate your model, and I came across an error stating, "Derivative input 1 is Inf or NaN. Stopping simulation. There may be a singularity in the solution." I noticed that @saiharshanaidu1486 also faced a similar problem. Can you assist me in resolving this issue?
Much appreciated!

can this be used for bidirectional operation, also couls ypu share the papers you used for reference

ОЧень интересно. Спасибо вам. Вы где-то выкладываете файлы проекта для симулинк?

Is it Critical conduction mode or triangular conduction mode.

Hi, i could replicate your model, the output of the current PI is completely saturated [-15,10] when the carrier is only [0,1]! This makes the mosfets to switch way faster than 40kHz (and uncontrolled), which is i think unacceptable in a real design.. what do you think? Im trying to design a control for a real prototype

what causes high ripple in the output ??

Thank you so much

我已成功运行，感谢，有需要的可以留言

I REPLICATED the same simulation but it is not working, my current IL is not sinusoidal and it is high varying from 0 to 2000 and Vout is not DC. kINDLY REPLY

can you give me the base paper link for this project

"Nice simulation! Could you share how you scaled the reference current (Iref) to match the inductor current (IL)? Did you determine it through trial and error, or did you follow a specific method? A guide on this would be really helpful, especially for scaling up to different power ratings. Looking forward to your insights!"
