Nesto oko hladjenja...
#35
Samo jedno pitanje, lici mi malo da idete u pogresnom smeru ili ja nisam ispravno shvatio zadatak, sta je cilj, da se testira hladnjak i/ili efikasnost montaze na hladnjak?
Ako je to zadatak onda ne moze tako da se pravi upravljacko kolo za tranzistor, mora Fead Back da ima jer se mnogo parametara tu mesa i 100W sijalica, cemu to?
Sto na sijalicu 100W, sto ne "samo" na tranzistor?

Kada se prati struja kroz tranzistor i odrzava na nekom fiksnom nivou i pri tome imamo fiksan ulazni napon mi tacno znamo koliko se discipira na tranzistoru. To je preduslov za sva dalja testiranja.

Sa trimerom na gejtu bez FB je besmisleno nesto iole korisno raditi, a najmanje ovo oko merenja efeikasnosti hladjenja, ne moze tako da se odrzi stabilan parametar struje, mnogo varira naspram temperature, pogledajte U/I krive za te tranzistore, nisu "prave" vec je to nelinearno podosta i to sve na razlicitim temperaturama.

Dakle, jedan OP, jedan shant i jedan tranzistor koji hocete, to se zatvori u strujnu regulacionu petlju i onda vam prakticno ne treba sijalica kao opterecenje, moze da bude u "kratkom spoju" a moze i sa sijalicom da se igra ko zeli.
