Designing harmonic filters for ups

(OP)
I am currently experiencing problems with harmonics generated by a 20KVA UPS. The 11th and 13th harmonics are the problem harmonics. I will like to design and install LC harmonic filters. What are the equations for this design and are there alternate solutions to this problem.
Thanks.

RE: Designing harmonic filters for ups

Are you talking about current or voltages ?

On the input or on the output?

Three Pase or Single Phase ?
