A Survey on Multilevel Rectifiers With Reduced Switch Count

This paper presents a literature survey of more than twenty years on AC/DC multilevel converters with reduced switch count, in which some power switches can be removed letting only diodes. simplification reduces the number gate drivers, cost and complexity system. In this work, considered topologies are derived from conventional configurations literature: Neutral Point Clamped, Cascaded H-Bridge, Flying Capacitor, Modular Multilevel Converter T-Type. article is divided five sections, each one papers previously mentioned. section, there up to maximum four subsections, considering main focus contribution: hybrid topologies, control techniques, analysis hardware design. At end summary table concerning referenced shown containing comparison information among presented references terms of: components per phase studied converter, applied modulation technique, suggested application given by authors, converter’s output respective efficiency point operation. With extensive bibliography serves as very good reference researchers interested topic initiate their work or update studies. Also, applications authors give direction fit best different applications.
