Hi please some one help


I am designing a Variable frequency motor Drive, (with threephase six pulse rectifier bridge LC filter and IGBT driver) for 3ph induction motor in 3hp,415v.The problem that I faced when doing the designing is that the calculating LC (inductive and capacitive) ripple filter values for the three phase rectifier bridge. So please be kindly help me by sending the appropriate formula for this.....
