Tool/software: WEBENCH® Design Tools
Hi guys,
this is my first post in this forum and I just joined the TI support network.
I'm trying to build a 230 V AC / 16 DC converter and to understand the
necessaray design I started to follow the equations mentioned in the
datasheet in chapter 9.
I already get stuck on page 18 calculating the CBULK value. I tried to
insert the values seen in table 2 in formular (2) and I can't reach the
resulting value of 15.6 µF mentioned on page 19.
Furthermore I do not understand the sentence on page 19:
"By using a full-wave rectifier allows a smaller capacitor for C1 and
C2, almost 50 % smaller." Using a full-wave rectifier would mean to
se for RCT a value of 2 instead of 1. The resulting capacity is almost
wice as bis as with a value of 1.
Can somebody help me on this? Since I'm not familiar with formular (2)
I'm not sure if I can trust calculated results when starting my own design.
BR,
Markus
