Rewinding atex transformer: The Atex transformers are High-frequency transformer. that only working with the frequency range from 20 kHz to 50 kHz. The atex transformer is in different type example EI33, EI28, EI41, etc. Atex transformer is mainly used in the SMPS and power amplifier ( car audio system ).
In this article, I’m going to share some ideas about how to recoil the atex transformer for making an inverter. 500 watts inverter using atex transformer. first, you need to disassemble the atex transformer if you need proper guidance on how to disassemble atex transformer?
Rewinding ATEX transformer
after disassembling the transformer we need to wind the primary coil to the transformer. The primary coil should be 3 turns center tap and again 3 turns using the copper wire of 22SWG ( 4 numbers ).
For secondary coil winding 90 turns with 23 SWG copper wire with proper layering and insulation. after winding primary and secondary coils solder the wires to the pins of the transformer. you are done. want more detailed explanation check this video tutorial.
