Reviewer 2 Report

This manuscript aims to investigate the principle, frequency characteristics and analysis of fractional-order LCL (FOLCL) filters. The authors introduce fractional-order inductors and fractional-order capacitors to replace the traditional integer-order components in LCL filters. The authors systematically investigate the principle and frequency characteristics of the FOLCL filter and derive five important properties that provide a theoretical basis for the design and application of FOLCL filters. The study provides a comprehensive analysis of FOLCL filters and offers valuable insights into their design, application and frequency characteristics. However, there are still some issues that should be addressed.
1. The lack of in-depth derivation and analysis. For example, the incorrect expression for the resonant frequency given in Ref. [41] needs further explanation. Does the study of Ref. [41] satisfy property (1)?
2. Equations (24), (25), (27) and (28) and the similar equations in the second case are ambiguous.

The manuscript as a whole needs to be proofread. It contains many linguistic and stylistic errors that need to be corrected. In addition, many sentences are too long, while many paragraphs are too short.
