trying to design a SMPS with constant current output.
input:
230Vac, 50Hz
Output:
constant current 150mA , 130V (Max Po=19.5W)
SMPS frequency is 60KHz
Ripple current ratio: 30%
I am a bit confused between the relationship of ripple voltage, ripple current and ripple factor.
1) how to calculate the output capacitor value to achieve the above ripple current ratio.
2) how to calculate the output capacitor value if I already have an inductor L in series (like a LC filter)
