Am facut multe feluri de amplificatoare. Cu TDA ,STK , si cu tranzistori de multe feluri,dar cu mosfeturi nu am facut nici unul. Vreau sa fac un amplificator puternic cu mosfet dar nu prea stiu ce schema sa aleg care si bun. Pina acuma am facut amplifuri pina la 2x120w. Vreau mai mare. Am transformator mare pregatit. Cum sa gasesc o schema ca lumea? Mosfetul trebe imperecheate in final sau nui obligatorie?

Inca ceva. Am un transformator 2x15,5 V curent alternativ si are cam 600 W. Bobinajul secundar are cam 2.5 mm grosime. Ce se poate face cu asta? Sau neaparat trebe bobinat la voltaj mai mare?

Din acesti 2 x 15,5V c.a. poti obtine aproximativ 2 x 21V c.c.....puteti face amplificatoare in punte cu integrate, de exemplu TDA2050 -2 bucati in punte-se preteaza f. bine la aceasta tensiune de alimentare....mai merge TDA1514A in punte care este superior lui TDA2050....

Sau faci o dublare de tensiune şi obţii o putere mai mare.

Cu reducerea la jumatate a curentului mediu disponibil, sau cu capacitori de valori mari, pentru a inmagazina energie suficienta pentru peak-urile de consum.
