Greeting! Everyone
I am making a DAB with an input of 400 V, an output of 48 V, an FSW of 50 kHz, and a power rating of 1 kW.
Also mention that the values I inserted are calculated: L1 is 4.6 µH, while Lp and Ls came from ANSYS Maxwell software, and the coupling coefficient K = 0.58 also came from it.
The issue is that my output should be 48 V, but it is still 21 V.
The MOSFETs I used are already built into SPICE, and they are compatible—you can check.
If anyone can help me find the libraries for the HV-side MOSFET SiHG039N60E-GE3, the LV-side MOSFET IRF80NF70, and the Si823 gate driver library, I would appreciate it.
Also, please help me understand how I can patch the gate-driver circuits into my simulation.

 

If you are representing your transformer as a separate inductor for the leakage inductance then you should set K to 1.
(If you wanted to let SPICE deal with the leakage inductance as part of the coupling coefficient than set K accordingly and remove the separate inductor).
I've never quite got the hang of K, so I always put in a separate inductor to represent the leakage inductance.

what do you mean by separate inductor ?here what should i separate it? L3 ? if i kept K= 0.58?
