Kothari, Senior Member, IEEE Abstract— Solid-state switch-mode rectification converters have developed using new solid state self commutating devices reached a matured level for improving power quality in terms of such as MOSFETs, insulated gate bipolar transistors (IGBTs), power-factor correction (PFC), reduced total harmonic distortion gate turn-off thyristors (GTO), etc., even some of which at input ac mains and precisely regulated dc output in buck, boost, buck–boost and multilevel modes with unidirectional and bidirec- have either not been thought or not possible to be developed tional power flow. This paper deals with a comprehensive review earlier using diodes and thyristors. Such pieces of equipment of improved power quality converters (IPQCs) configurations, con- are generally known as converters, but specifically named trol approaches, design features, selection of components, other re- as switch-mode rectifiers (SMRs), power-factor correctors lated considerations, and their suitability and selection for specific (PFCs), pulsewidth-modulation (PWM) rectifiers, multilevel applications. It is targeted to provide a wide spectrum on the status of IPQC technology to researchers, designers and application engi- rectifiers, etc. Because of strict req
