Abstract

Abstract : This study provides the design, control and comparative analysis of the proposed LCLC coupling hybrid active power filter (LCLC‐HAPF). Compared with the conventional L filter coupling active power filters (APFs), LC filter and LCL filter coupling HAPFs (LC‐HAPFs and LCL‐HAPFs), the proposed LCLC‐HAPF provides better switching frequency harmonics elimination, lower dc‐link voltage rating and switching loss. Although the LCLC‐HAPF has some advantages, two main challenges will still be confronted in practical implementations. Those are stability problems caused by resonance of LCLC filter, and parameter design for the LCLC filter. In this study, a new active damping method is proposed to overcome the high order resonance problem existing in the proposed LCLC‐HAPF. After that, the stability analysis and parameter design are given for the proposed LCLC‐HAPF. Finally, the effectiveness of the proposed LCLC‐HAPF topology is validated through both simulation and experimental studies in comparison with the conventional APFs and HAPFs.
