Abstract—Three-phase ac–dc converters have been developed to a matured level with improved power quality in terms of power-factor correction, reduced total harmonic distortion at input ac mains, and regulated dc output in buck, boost, buck–boost, multilevel, and multipulse modes with unidirectional and bidirectional power flow. This paper presents an exhaustive review of three-phase improved power quality ac–dc converters (IPQCs) configurations, control strategies, selection of components, comparative factors, recent trends, their suitability, and selection for specific applications.
It is aimed at presenting a state of the art on the IPQC technology to researchers, designers, and application engineers dealing with three-phase ac–dc converters. A classified list of around 450 research articles on IPQCs is also appended for a quick reference.
Index Terms—Harmonic reduction, improved power quality, power-factor correction, switch-mode rectifiers, three-phase ac–dc converters.

HREE-PHASE ac–dc conversion of electric power is widely employed in adjustable-speeds drive (ASDs), uninterruptible power supplies (UPSs), HVdc systems, and utility interfaces with nonconventional energy sources such as solar photovoltaic systems (PVs), etc., battery energy storage systems (BESSs), in process technology such as electroplating, welding units, etc., battery charging for electric vehicles, and power supplies for telecommunication systems [1]–[25]. Traditionally, ac–dc converters, which are also known as rectifiers, are developed using diodes and thyristors to provide controlled
