/challenges-projects/design-challenges/experimenting-with-flyback-transformers/b/blog/posts/flybacks-from-the-ground-up---part-1-introduction-unboxingThanks to element14 and Bourns for selecting me as one of the challengers for the Experimenting with Flyback Transformers Design Challenge. Power conversion is a key part of modern electronics designs and almost every low-power, low-cost, energy-effien-USTelligent Community 12https://community.element14.com/challenges-projects/design-challenges/experimenting-with-flyback-transformers/b/blog/posts/flybacks-from-the-ground-up---part-1-introduction-unboxingTue, 16 Jan 2024 19:40:25 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:72687af8-3bd7-4513-b7cd-da7941c32a92DAB0<p>Nice overview of the kit.</p><img src="https://community.element14.com/aggbug?PostID=27445&AppID=432&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/experimenting-with-flyback-transformers/b/blog/posts/flybacks-from-the-ground-up---part-1-introduction-unboxingTue, 16 Jan 2024 15:29:01 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:72687af8-3bd7-4513-b7cd-da7941c32a92shabaz1<p>Very detailed photos!&nbsp;</p> <p>Regarding the crossed secondary wires, I guess the winding machine was set up to operate in one direction, and they may have wanted the secondary side to be oriented with the beginning of its winding at the same end as the primary side beginning. The photos help a lot, the datasheets are sometimes not easy to follow to understand the pin numbering direction : (</p> <p>(Although the worst offender there is Minicircuits who sometimes mark the <em>last</em> pin with a dot, instead of pin 1! )</p><img src="https://community.element14.com/aggbug?PostID=27445&AppID=432&AppType=Weblog&ContentType=0" width="1" height="1">
