Idee despre amp clasa D putin mai neobisnuit...


Recommended Posts

Salut. M-am gandit sa fac un amp dintr-o sursa PC ATX in felul urmator:

1. Amplif. sa functioneze in clasa D

2. Tensiunea de 5VSB sa asigure functionarea integratului KA7500 (sau echivalent)

3. Tranzistorii de comutatie din circuitul primar sa-mi moduleze practic tensiunea de intrare cu ajutorul integratului KA7500 (sau echivalent)

4. Iesirea pe difuzor sa fie facuta de pe chopper (eventual cu un filtru LC)

5. Folosirea a minim 2-3mF filtrare pe primar in locul filtrarii obisnuite (2x220-2x680uF)

 

Credeti ca acest proiect ar fi viabil? Merita dezbatut sau nu? Ca daca nu merita dezbatut, se poate arunca la cos.... :axe:
