Am un traf de 2*30V cu 5A legat la 8x 4 600uF/63V + 8x100pF/100V si ajunge in timp de la -43,0,+43 (in sarcina) la -49,0,+37.(am avut si condensatori care au facut bumm...)Ma intereseaza un etaj de stabilizare (problema sunt cei 5A)

Am un traf de 2*30V cu 5A legat la 8x 4 600uF/63V + 8x100pF/100V si ajunge

in timp de la -43,0,+43 (in sarcina) la -49,0,+37.

(am avut si condensatori care au facut bumm...)

 

Ma intereseaza un etaj de stabilizare (problema sunt cei 5A)

curentul (amperajul) printr-un circuit este dat de consumator.

 

zi mai exact care e problema, se modifica tensiunea in sarcina? ca nu inteleg

tensiunea de alimentare e cam mare pentru Tda7294.

 

cele doua infasurari ale trafului sunt facute corect? masoara si tensiunea trafului in sarcina.
