In the LCL filter, the calculation result of the calculation factor r of the inductance Lgrid and the inductance Linv is wrong.As shown below.

According to the calculation formula (6) of r, the calculated result is 56% instead of 2.7%, and the calculated value of Lgrid is also wrong. Therefore, if the calculation formula of r is correct, please give a correct answer.
