Restricted interleaving phenomenon in Interleaved Boost PFC with leg sharing APF circuit

Abstract

The paper proposes an interleaved Power factor correction (PFC) Rectifier integrated active power filter (APF). The interleaving helps to reduce individual switch stress and improves input current by reducing the ripple. While integrating the interleaved structure with APF, an inherent problem of the structure becomes prominent and creates disturbance in both PFC and APF. The problem is discussed thoroughly and remedy proposed by introducing the diode leg. © 2022 IEEE.
