i probably don't recognize the tl431 and uc 3879 products because I'm using the current version of my system. will you use equivalent products and share the working circuit with me _?the current version I am using right now.version (x64): 24.1.9

Hi umit,
the UC3879-file was uploaded by several other users in our group, and no problems occured.

I am attaching the files again. Make sure that all files are in the same directory !!
Where have or did you place(d) your other working files, in which directories? How did you organize your personal working folders. ?

First of all, thank you very much for your return. . I downloaded the files you sent again and saved them all in the same directory. I will try it again from the beginning. It gave me a warning like this, but I said OK and continued, just so you know. and finally he gave a warning.

• First of all, thank you very much for your return. . I downloaded the files you sent again and saved them all in the same directory. I will try it again from the beginning. It gave me a warning like this, but I said OK and continued, just so you know. and finally he gave a warning. But it worked, is there anything you need to update about it?i think there is a problem with the mmbz18val and 2scr293p equipment.Besides, I have a favor to ask of you .
  
  --I need to add a novelty to my circuit and I have 2 options, can you help me with this?
  
  1- Bidirectional PSFB (Bidirectional) + Battery Charger/DischargeUsing
  the PSFB in both charger and discharge modeBidirectional PSFB (Bidirectional) + Battery Charger/Discharge
  
  
  2- Multi-Mode PSFB (with ZVS ↔ ZCS pass-through)
  Can we make the circuit able to select the most appropriate resonance mode according to the load condition?
  If the load current is low: Switch to ZCS mode.If the load current is high: Stay in ZVS mode.
  Innovation: Dual-mode resonant switching control algorithm → high efficiency over a wide load range.

Umit, your error message means, you do not have those elements in your library ! If I am right, the missing transistors are in the standard lib of LTspiceXVII.
The best is, you check for LTspice updates. Then you will get more components, filling up your standard library. The standard lib components are in a directory named "cmp".
Another possibility is you search for other transistors which are listed in your library and offer voltage and current requirements for the driver circuit.
