Abstract

A single phase grid-connected converter is usually adopted in low power renewable systems. This paper deals with a review of the state of the art of multi level topologies and a theoretical power loss comparison with the proposed solution is compared. The proposed converter architecture is based on a full-bridge topology with two additional power switches and two diodes connected to the midpoint of the dc link. Since the two added levels are obtained by the discharge of the two capacitors of the dc link, the balancing of the midpoint voltage is obtained with a specific pulse width modulation (PWM) strategy, Multilevel converters have been under research and development for found successful industrial application. This is still a technology under development and many new contributions and new commercial topologies have been reported in the last few years advances made in modulation and control of multilevel converters are also addressed. A great part of this paper is devoted to show nontraditional applications powered by multilevel converters and how multilevel converters are becoming an enabling technology in many industrial sectors.
