Tapped Inductor in Cuk-Buck 2
Altair EmployeeHi there
I am trying to reproduce the recently popularized Cuk-Buck 2 topology in PSIM and facing a little problem with the tapped inductor model. Can anyone please guide me a little. Moreover, I believe Albert was also working on this topology, it would be a great help if you can share your simulation file.
Thanks

Altair EmployeeHi Albert
Thank you for your reply.
I am sorry to inform you that I have PSIM version 9.0. Can you please save these schematics to the previous version and attach again?
Thanking in advance.

Altair EmployeeHi Sahil,
Please see the attached. Also, if you are a student your instructor can request free teaching licenses:

Hi Sahil,
2 circuits attached, one cuk-buck2 has deadtime and some caps parallel to the switches to try and get some ZVS and ZVC, these caps are not really well thought out and need to tuned.
The other cuk-buck 2 is a straight reproduction of his circuit with component values visible from these videos.

Dr. Cuk claims a number of things, like 99% efficiency and fast transient response. I don't see how any of these are true.
