DC Link Capacitance

[Phaneas]

Hello,

I have to calculate the necessary dc link capacitance for a VFD. Does anybody know a good book or other documents how this is calculated. Couldn't find too much in the net.

Thanks in advance.

Hello,

I also found this one here:

What Voltage ripple in % is normally used for the calculations?
