TRANSFORME QUALQUER FONTE CHAVEADA em FONTE SIMÉTRICA com ajuste de tensão

In this video, I teach step-by-step how to transform a 12V automotive switched-mode power supply into a symmetrical power supply for a class D amplifier or for bench use. I practically demonstrate the difference between the original 12V board and the modified prototype, explaining which components need to be changed in the transformer, diodes, capacitors, and feedback loop. I also show in the TL431 circuit which components should be removed and adjusted so that the power supply works correctly in the symmetrical configuration. ⚠️ Warning: This procedure requires knowledge of switched-mode power supplies. Only do this if you have experience and always with due care. This video is a continuation of the content about the TL431, where I explained the operation of the regulation loop. If you want to learn in practice how to adapt your automotive power supply to power amplifiers or assemble a symmetrical power supply for a bench, this video is for you.
