Sunt nou intrat pe site-ul asta si sunt si incepator in electronica.As avea nevoie daca ma poate ajuta cineva cu o schema de convertor AC-DC, sa fie cat mai simpla, sa converteasca tensiunea de la retea in tensiune mai mica.Astept niste raspunsuri de la voi.

adica ai nevoie de un transformator, o punte redresoare (4 diode) si un condensator de filtraretensiunea obtinuta va fi aprox 1.41*tensiunea din secundarul transformatoruluidaca ai nevoie de o tensiune DC stabilizata trebuie sa stii ce valoare ai nevoie si mai pui si un regulator de tensiune pentru valoarea respectiva. de exemplu pt 12V pui circuitul integrat 7812
