How to design LC filter using MATLAB for Multi-level inverter output??

I am looking for filtering the voltage output of a multilevel inverter to get a pure sinewave.

I'd like a clear way to describe the steps that can be taken to get what I want.

I tried by using modified multilevel inverter with LC filter with utlizing these parameter

L= 3e-3

C= 470e-6

Vin= 200v

Rload= 100

However, the multilevel inverters signal is distorted, and the output voltage after LC filter is not a pure sine wave..

These pictures are of a multilevel inverter signal without a filter and the second with a filter.

thanks in advance

Did you find a answer for this? How did you find this?
