Como Enrolar TRAFO de PULSO na FONTE Chaveada Automotiva

Pulse Transformer. In this video, I show, from beginning to end, a completely practical and detailed project with a high-current power supply board, focusing especially on the pulse transformer and the actual operation of PWM in the primary stage. Right at the beginning, I present some components that I am sending as a gift to one of the channel members, who also actively participates in our exclusive members' group on WhatsApp. After that, I go straight to the technical part, without any beating around the bush, with content designed for those who really like electronics explained in practice. Throughout the video, I do a complete analysis of the PWM on the oscilloscope, showing frequency, peak voltage, and the signal behavior directly on the pulse transformer and in the drive stage of the power supply devices. Everything is shown calmly, open screen, few cuts, and clear explanation, precisely to facilitate understanding. Next, I go into the complete winding process of the pulse transformer, using the small toroidal core. I show the core, explain the number of wires, the number of turns, the winding organization, and all the necessary precautions to avoid mistakes. I also explain how to correctly identify the primary and secondary windings, avoiding polarity reversal during installation. After winding, I install the transformer on the board, explaining step by step how to solder correctly and how to check everything before turning it on. Next, I perform comparative tests, showing on the oscilloscope the difference between the original transformer and the wound transformer, comparing frequency, peak voltage, and PWM behavior. It's a very straightforward video, with little editing and a total focus on the real step-by-step process, designed for those who really want to learn, whether for maintenance, study, or technical improvement. Throughout the video, other important details appear that make a difference in the day-to-day work of those who work with switched-mode power supplies and power electronics. If you like technical content, explained calmly and without shortcuts, this video is for you. #powerfuluniversalpowersupply #pulse transformer #electronics #amplifier #electronicdiagnostics #switchedpowersupply #electrician #pulsetransformerinstallation #jfapowersupply #pwm
