stabilizator 220V~

Recommended Posts

am deschis acest topic deoarece acasa ma confrunt cu urmatoarea problema: in timpul zilei tensiunea de la reteaua publica scade pana la 180-190V :rolleyes: si variaza ca atunci cand folosesti un transformator de sudura la una din prizele locuintei , noaptea tensiunea ajunge pe la 220v. ma gandesc sa redresez curentul de la priza sa sa fac un smps cu oscilator in 50-60 hz ,prevazut cu retea de feedback astfel incat sa mentina constanta tesiunea de iesire,tot montaju sa aiba vreo 2 KW insa nu am decat o schema de smps in contratimp care necesita transformator la iesire.are cineva o schema simpla de sursa in comutatie fara transformator?daca aveti alta idee pentru stabilizare la 220 in ca va rog sa o postati :prayer:

Cred ca te-ar ajuta si asta: intreaba-l pe gogu de "ferroresonant transformer" sau "constant-voltage transformer". Asa ceva se folosea pe vremuri in zonele rurale.Cirip
