Applications of cascade multilevel inverters
Journal of Zhejiang University-SCIENCE A, 2003Cascade multilevel inverters have been developed for electric utility applications. A cascade M-level inverter consists of (M-1)/2 H-bridges in which each bridge's dc voltage is supported by its own dc capacitor. The new inverter can: (1) generate almost sinusoidal waveform voltage while only switching one time per fundamental cycle; (2) dispense with ...

Cascaded multilevel inverter using sub-multilevel cells
Electric Power Systems Research, 2013Abstract The multilevel inverters have been in the center of focus of many researcher in recent years. This is partly because of some advantages such as improved output power quality. The multilevel inverters can generate a near sinusoidal output voltage. The quality of output voltage depends on the number of voltage levels of inverter.

Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting., 2004
This paper presents a new class of multilevel inverters based on a multilevel dc link (MLDCL) and a bridge inverter to reduce the number of switches, clamping diodes, or capacitors. An MLDCL can be a diode-clamped phase leg, a flying-capacitor phase leg, or cascaded half-bridge cells with each cell having its own dc source.

Multilevel inverter by cascading industrial VSI
IEEE Transactions on Industrial Electronics, 2002In this paper the modularity concept applied to medium-voltage adjustable speed drives is addressed. First, the single-phase cascaded voltage-source inverter that uses series connection of IGBT H-bridge modules with isolated dc-buses is presented. Next, a novel three-phase cascaded voltage-source inverter that uses three IGBT triphase inverter modules ...

Overdistention operation of cascaded multilevel inverters
IEEE Transactions on Industry Applications, 2003Established research has shown that cascaded multilevel inverters can provide more voltage vectors per number of active semiconductors compared to typical multilevel converters. This feature is significant for increasing the drive performance as well as reducing the drive complexity and losses.

Multilevel inverter as var-compensator
2013 IEEE XXXIII International Scientific Conference Electronics and Nanotechnology (ELNANO), 2013Multilevel inverter consists of base cells that have the same structure as active power line conditioner. This allows to use the inverter cells as the VAR-compensator in uninterruptible power supply systems. The advantage of this system is increasing the allowable current range that can be correctly compensated.
