Ρε παιδια ή κατι δεν καταλαβαινω εγω καλα, ή στραβα αρμενιζουμε.
Στην σελιδα 7 του datasheet του LT4320 (http://cds.linear.com/docs/en/datasheet/4320fb.pdf) γραφει:
A good starting point is selecting C LOAD such that:
C LOAD ≥ I AVG /(V RIPPLE • 2 • Freq)
where I AVG is the average output load current, V RIPPLE is
the maximum tolerable output ripple voltage, and Freq
is the frequency of the input AC source. For example, in
a 60Hz, 24VAC application where the load current is 1A
and the tolerable ripple is 15V, choose C LOAD ≥ 1A/(15V
• 2 • 60Hz) = 556μF.
Ειναι ποτε δυνατον να ειναι αποδεκτο ripple 15V????
