Hello

I am designing my active power filter circuit in hardware design. I calculate the system parameters using the formula. I am confused on some points in my system designs.

1. The values in simulation are different than formula parameters in case of inductances.

2. How can I install the inductance towards the source side and load side? I mean do I have to use the transformer or separate inductance or source or line inductance?

3. My work is in active power filters, so I have to design the source and load prototype and which values I can used (Simulation one or formula one). 

Kindly guide me in this matter. Thanks
