In current source inverters

(a) L filter is used after the CSI (load side)

(b) L filter is used before the CSI (input side)

(c) C filter is used after the CSI (load side)

(d) C filter is used before the CSI (input side)

I had been asked this question during an interview.

Right choice is (b) L filter is used before the CSI (input side)

For explanation I would say: In order that the current input to the CSI must remain ripple free an constant, L-filter is used before the CSI (in series with the energy source).
