Hi Everyone , I'm designing a VFD for final year project ,
Just wondering if anyone could shed some light on calculations for a smoothing capacitor for for a 6 IGBT H bridge , with 3 Phase Diode Rectifier , converting ac to dc bus .
The input AC V is 175 50 Hz at 44A across 3 phase at 0 , -30 , -60 degrees . My IGBT's are rated for 600v 100 A .
I would like to have the ripple voltage around 4 % .
