Multilevel inverters are suited for high power drive applications due to their increased voltage capability. Specifically, as compared to three level inverters, for a given dc bus voltage, a four-level inverter is able to synthesize better waveforms with reduced device ratings. In a medium voltage drive, a conventional diode bridge rectifier is a low cost multilevel solution if the dc bus volta...

this paper presents a grid connected photovoltaic system, which acts as both power generator and active power filter (apf), based on flying capacitor multicell (fcm) converter. increase in the number of output voltage levels, natural self-balancing of flying capacitors and dc link voltage and lower power rating of components are the main futures of fcm converter compared with conventional multi...

Abstract. A new Modular Marx Multilevel Converter, MC, is presented. The MC topology was developed based on the Marx Generator concept and can contribute to technological innovation for sustainability by enabling wind energy off-shore modular multilevel power switching converters with an arbitrary number of levels. This paper solves both the DC capacitor voltage balancing problem and modularity...

Capacitor voltage balancing is of importance in the neutral-point-clamped based dual-active-bridge converters. Most traditional methods adopt transformer current models process, as direction neutral-point affected by polarity. However, this approach requires heavy and repetitive offline precalculation for polarity under various operating modes, thus, leading to complicated implementation. To ov...

Abstract This paper proposed a new voltage-boosting 13-level switched-capacitor (SC) cost-effective inverter. The topology comprises fourteen transistors, three capacitors and single DC source to produce staircase waveform. capacitor voltage balancing problem is inherently solved by the series/parallel technique. Structural description, working principle, calculation of optimum values capacitan...

Cascaded H-bridge multilevel power electronic converters generally require several dc sources. An alternative option is to replace all the separate dc sources feeding the H-bridge cells with capacitors, leaving only one H-bridge cell with a real dc voltage source. This will yield a cost-effective converter. However, the required capacitor voltage balancing is challenging. In this paper, using t...
