Multicarrier PWM strategies for multilevel inverters
IEEE Transactions on Industrial Electronics, 2002Analytical solutions of pulsewidth-modulation (PWM) strategies for multilevel inverters are used to identify that alternative phase opposition disposition PWM for diode-clamped inverters produces the same harmonic performance as phase-shifted carrier PWM for cascaded inverters, and hybrid PWM for hybrid inverters, when the carrier frequencies are set ...

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 ...

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 ...

Fault tolerant multilevel inverter
i-manager's Journal on Power Systems Engineering, 2022The steady rise in energy demand, combined with the loss of conventional resources, spurs research into environmentally benign renewable energy sources like solar and wind. These sources are appropriate for rural, urban, and offshore areas because to their ease of installation, low operating costs, and copious supply (sun light and wind).

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.

ANALYSIS OF A GENERALIZED SYMMETRICAL MULTILEVEL INVERTER
Journal of Circuits, Systems and Computers, 2011The cascade multilevel converter requires the least number of main components among traditional multilevel converter. In this paper, comparison of main components between proposed and traditional converter is shown. In addition, a generalized symmetrical multilevel inverter is proposed.

A Different Multilevel Current-Source Inverter
IEEE Transactions on Industrial Electronics, 2010DC/AC converters are widely used in several applications; traditionally, they can be classified in two types: the voltage-source inverters (VSIs) and the current-source inverters (CSIs). Their use depends on their application; however, some of them are common for both types of converters.

Nonlinear optimal control for multilevel inverters
2019 IEEE 28th International Symposium on Industrial Electronics (ISIE), 2019The article proposes a nonlinear optimal (H-infinity) control approach for the model of modular multilevel inverters. The article’s results are of interest for power grid applications were to handle high voltage one can use low voltage semiconductors.

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.
