    Size of the LCL filter damper resistor

    Hi All,
    I am designing LCL filter for a grid-connected converter. I am wondering how can I calculate the damper resistance power?


    Thank you for your comments,

    It will be exactly 0.2% of the total kVA of the GCI .....

    Careful Peasy, even I did a double take here...

    Re: Size of the LCL filter damper resistor

    I searched and I found this. The calculation sounds correct in this paper, so we can calculate by using this paper:
    IEEE TRANSACTIONS ON POWER ELECTRONICS, VOL. 28, NO. 6, JUNE 2013
    Analysis of the Passive Damping Losses in LCL-Filter-Based Grid Converters
