Ce forma de unda ar avea tensiunea dupa iesirea din circuit.

Daca folosesti jucaria aia din link-ul de mai sus, poti redresa rezultatul obtinut cu o punte redresoare si condensatori de filtraj pentru o sursa de curent continuu (reglabila).

Daca merge, poti combina doua chestii de genul ala pentru a face o sursa de CC simetrica?

 

E vreun risc? Izolatie galvanica?

Nu dau de schema, dar la cat e de simplu, banuiesc ca una din iesiri vine direct de la retea...

Merge trecuta apoi printr-un traf 1:1 ca sa ai si izolvatia galvanica?
