hai,
i happen to see the reference design of a Grid tie based micro solar inverter from ti.
can you please share me the design document ,or how calculations were done to implement the LCL filter design in the grid tie section.Is this the way to implement the Grid Tie? How were the values of Li,Lg and Cf calculated?How was the value of L11 calculated in the design.Actually do we need that?am asking this because i couldn't find the induct or either calculated or implemented in TI Grid connected reference design:
www.ti.com/.../tievm-hv-1ph-dcac
Actually which is the correct way of implementing LCL?i have attached the screen shot of both reference designs:
Please hep me with this doubts.Since my project is in a critical stage, fast response is expected.
