ABSTRACT

A new operational mode for diode-clamped multilevel inverters termed quasi two-level operation is proposed. Such operation aims to avoid the imbalance problem of the dc-link capacitors for multilevel inverters with more than three levels and reduces the dc-link capacitance without introducing any significant voltage ripple at the dc-link nodes. The proposed operation can be generalized for any number of levels. The validity of the proposed multilevel inverter operational mo ....etc

A MODULAR FUEL CELL, MODULAR DC–DC CONVERTER CONCEPT FOR HIGH PERFORMANCE AND ENHANCED RELIABILITY
ABSTRACT
Fuel cells are electrochemical devices that process H2 and oxygen to generate electric power, having water vapor as their only by-product. The voltage resulting from the reaction of the fuel and oxygen varies with the load, and ranges from 0.8 V at no-load to about 0.4 V for full-load. Due to their low output voltage, it becomes necessary to stack many cells in series to realize a practical system. The propos ....etc

This paper highlights some effects of an asymmetrical design on three phase multilevel inverters from a supply network point of view. The investigated topology is based on a series connection of single phase inverters (partial cell) in each phase. Each partial cell is fed through a three-phase diode rectifier for a unidirectional power flow, fed itself through the secondary of the power transformer (PT). From analytical relationships in continuous and discontinuous current conduction mode, itâ„¢s shown that a symmetrical multilevel inverte ....etc
