Hi Eternity and TechSim crowd... Did you figure this out? I have an initial rapid spike of 0 to 350 or 400V and then linear drop to steady 100V. Thanks, Dan...
yes, but need to change the diode to mosfet. My simulations are not based on any reference paper. i am just sharing my knowledge. But still you can get related papers from internet.
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
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
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
@@TechSimulator Was this issue resolved? Im attempting to replicate also and would like to know. Thank You, I appreciate your work here, it is really fantastic to see this. Thanks, Dan...
To update on this. I dont have this issue with my model. I do have Output Block warning of Open Ports on the FETs and Diodes on Port E. Also currently I have an initial voltage spike and then a steady 100V. Looking into that now. Dan...
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!
Thanks!
Hello and thank you for the video.
How do you tune the PI controller parameters please ?
Thanks again
Awesome! Thank you very much for your content!
👍
Hi, thanks for the video.
But there is a huge current spike in the input side current. How can we remove that? Please reply.

I found my error (incorrect schematically) and it now runs like TechSims.
what causes high ripple in the output ??
can this be used for bidirectional operation, also couls ypu share the papers you used for reference
yes, but need to change the diode to mosfet. My simulations are not based on any reference paper. i am just sharing my knowledge. But still you can get related papers from internet.
can you give me the base paper link for this project

I also got the same trouble
@@anywarthomas4914 me too :(
Is it Critical conduction mode or triangular conduction mode.

No that is not acceptable. Looks like something wrong with the controller. I haven't checked that, let me check it.
One suggestion, try limiting the current controller output between 0 to 1, and see what is happening.
Good video
Thanks
Thank you 👍
ОЧень интересно. Спасибо вам. Вы где-то выкладываете файлы проекта для симулинк?
нет
Try all 4 switches as MOSFET and implement the simulation
Will do
Thank you so much

Pls mail the model
Hi there, I also got same problem. Did you find the solution yet ?
Hi , how you solved this error ?

We need videos on DAB converter

Make a vido on bidirectional AC/AC converter
