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.

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.

Es wäre cool, wenn ihr die englischen Fragen auch in "Translater-deutsch" posten könntet, da wir ein deutschsprachiges Forum sind

YOU ARE RIGHT, I APOLOGIZE. I WAS A LITTLE DISTRACTED. WRITING AND SENDING IN TURKISH WAS A MISTAKE.

Umit, ich werde mir über deine Fragen Gedanken machen.

Vorher würde mich noch interessieren, ob Du die existierende Schaltung des Phase-shift converters simulieren konntest ? Wenn nicht, brauchen wir über Anpassungen noch nicht nachdenken.

JA, ICH HABE ES GESCHAFFT, VIELEN DANK . WIR HABEN ES MIT DER LETZTEN SCHALTUNG AUSGEFÜHRT, DIE SIE GESENDET HABEN

1.Bidirectional PSFB (Bidirectional) + Battery Charge/DischargeUsing the PSFB in both charge and discharge mode Bidirectional PSFB (Bidirectional) + Battery Charge/Discharge
Antwort: Der Phase-Shift Converter, bestehend aus der aktiv angesteuerten Brücke mit den 4 MOS Transistoren auf der Eingangsseite und der Diodenbrücke auf der Ausgangsseite kann nur Energie von der Eingangsseite auf die Ausgangsseite übertragen. Der umgekehrte Energiefluss von der Ausgangsseite zurück zur Eingangsseite ist mit dieser Schaltung nicht möglich.
Um die Energieübertragung nach beiden Seiten, also vom Eingang zum Ausgang und vom Ausgang zum Eingang zu ermöglichen, muss die Diodenbrücke durch aktive Schalter (z.B. MOS-Transistoren) ersetzt werden.
Eine solche Schaltung ist unter dem Namen DAB (Dual Active Bridge) bekannt.
Die Steuerung eines DAB-Konverters im Dual-Modus ist komplex, da sie den Stromfluss in beide Richtungen regeln und die Spannungen an beiden Seiten des Konverters stabilisieren muss. Üblicherweise wird die Phasenverschiebungsmethode verwendet, um den Leistungsfluss zu steuern. Dabei wird die Phasenverschiebung zwischen den beiden Brücken des Konverters angepasst.

Ich habe dazu 2 Artikel angehängt. Außerdem noch eine LTspice-Simulationsschaltung eines DAB-Converters. Die Anpassung der Signale für den bidirektionalen Energiefluss ist hierbei aber nicht eingearbeitet. Man müsste dafür die Signale für den Buck-Betrieb (vom Ausgang zum Eingang) anpassen. Das ist aber sehr umständlich und nicht sehr praxisgerecht. Deshalb wird dafür meistens ein Mikrkontroller eingesetzt. Leider sind solche Komponenten für LTspice nicht verfügbar. Eine Simulation lässt sich deshalb damit nicht realisieren.

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 wide load range.
