I am designing the 3-phase motor driver using 6 IGBT and 3 IR2110 drivers...

I want to use RCD snubber circuit like shown in the attached file...but I don't know how to calcullate R,C and D....my details for the supply and motor are----Vbus=230V ... R=5 ohm between each windings...

now I have checked the circuit with low voltages (~15V)... so I don't know other parameters...can u help me out??

how to know ripple voltage? how to calculate peak current?

Actually I found one website which can calculate parameters...but I am not able to crack...
