High Frequency switching transformer

Anyone tell me how can i design transformer or download the library for kicad of high frequency transformer

Before designing in KiCad, you need to determine:

Operating frequency (kHz to MHz range)
Power rating (Watts)
Turns ratio (Np:Ns)
Core material (Ferrite, Powdered Iron, etc.)
Winding type (Litz wire, planar, etc.)
Inductance & Leakage requirements

Use tools like LTspice, ANSYS Maxwell, or Simplis for simulation before PCB implementation.

You’re welcome.

Hi,

Welcome to the Kicad forum.
Just a FYI, generally speaking, we try to keep the forum solely for Kicad (the software) related problems and NOT general electronic howto’s. Now, if someone feels generous, they might opt to answer these types of questions but it is not guaranteed.

EEVBLOG (plilus others) are more geared towards electronics and electronic design questions. Once you have a design and want to make a.PCB this is where Kicad comea into play.
