A New Interleaved Three-Phase Single-Stage PFC ACDC Converter With Flying Capacitor

Abstract

A new interleaved three-phase PFC acdc single-stage multilevel is proposed in this paper. The proposed converter can operate with reduced input current ripple and peak switch currents due to its interleaved structure, a continuous output inductor current due to its three-level structure, and improved light-load efficiency as some of its switches can be turned ON softly. In the paper, the operation of the converter is explained, the steady-state characteristics of the new converter are determined, and its design is discussed. The feasibility of the new converter is confirmed with experimental results obtained from a prototype converter, and its efficiency is compared to that of another multilevel converter of similar type.
