se pare ca awelco ondulix 140 a fost facut in decursul timpului in mai multe variante, respectiv dupa mai multescheme electronice, varianta cu ucc3580 fiind printre primele in topografia active clamp forward convertor.Incerc si eu sa repar acum un invertor awelco ondulix 80, in aceiasi topografie si intrucit nu am gasit nicaieri o schema am solicitat de la awelco direct, acestia fiind amabili mi-au trimis o schema care este comuna pentru ondulix 80 si 140, diferit fiind nr de tranzistori pusi in paralel, insa schema nu este completa neavind si schema placilor PWM si RCA(au spus ca e prea veche varianta si nu le mai au). Daca doriti schema in varianta aceasta o pot trimite pe mail. UCC3580 am comandat chiar astazi la RS, si costa cam 6,5euro+tva+transport. Se pare ca acum a aparut UCC2897A care este mai bun decit UCC3580, avind reglaj in curent nu in tensiune insa trebuie reconstruita placuta PWM. UCC2897 costa cca 3,5euro+tva.
