Comanda electronica a unor curenti mari


Recommended Posts

As dori sa incep acest topic pentru a primii sfaturi si sugestii pentru urmatoarea problema :)Vreau sa controlez curenti relativ mari intr-un mod electronic...Cred ca un exemplu pe care am putea incepe o discutie ar fii comanda unui motor de 24V si aproximativ 10A (o putere teoretica de 240 - 250W) printr-un sistem H-brigde, avand la baza o comanda electronica a unui microcontroller (sau sistem Arduino)Astep sugestii sau comentarii (pro/contra) pentru relee, tranzistori, tiristori, circuite integrate etc. icon_jook

Apoi, imi va face placere sa-ti raspund la intrebari legate de puntea H.

 

Un exemplu concret, care a evoluat mult intre timp, dar bun ca punct de pornire (si ca sa stii ce sa nu faci :da ): http://mirceablog-electronics.blogspot.ca/2011/12/16f690-rc-esc-speed-controller-full.html
