I have made predictive current control for dc to ac two level 3 phase. When doing THD analysis i get 8.39% whereas 5% is acceptable. How can i get the desired THD levels
may be you can put some LC filter in the load side...else you can use some suitable PWM switching patterns like APOD and POD...
You can try varying the level if possible or width .
Cheers
@Vishal Charan
You can try following
1. Increase the switching frequency.
2. Check the harmonic numbers present in the current. Accordingly design filter remove those harmonics.
