Topologies for regenerative cascaded multilevel inverters
IEEE 34th Annual Conference on Power Electronics Specialist, 2003. PESC '03., 2003This paper presents a comparison of several regenerative cascaded inverters and introduces a new topology with a reduced number of power semiconductors. The control strategy of the converters is discussed in detail and results are provided to evaluate the topologies and the control methods.

Improved performance of cascaded multilevel inverter
2016 International Conference on Microelectronics, Computing and Communications (MicroCom), 2016Cascaded H-Bridge (CHB) Multi-Level Inverter (MLI) is widely known for their better performance. This topology is very widely used in renewable applications due to its advantage in the availability of isolated DC links. However, in MLIs the main constraint lies in the usage of switches, so as to avoid the switching losses.

Switching Characterization of Cascaded Multilevel-Inverter-Controlled Systems
IEEE Transactions on Industrial Electronics, 2008In this paper, the method of triangular carrier switching control of two-level inverters is extended to cascaded multilevel inverters using phase-shifted multicarrier unipolar pulsewidth modulation (PWM). The condition for smooth modulation is obtained using the Bessel's function representation of the PWM output and the switching condition of the ...

Cascaded Multilevel Split-Source Inverters: Analysis and Modulation
2019 21st International Middle East Power Systems Conference (MEPCON), 2019A new cascaded multilevel inverter topology is proposed in this paper. This topology extends the idea of the recently introduced Split-Source Inverter (SSI) to the cascaded Multi-Level Inverter (MLI) configurations. This structure provides the boosting capability in conjunction with the dc to ac conversion in a single unit with reduced passive elements.

Transformerless series sag compensation with a cascaded multilevel inverter
IEEE Transactions on Industrial Electronics, 2002The use of a cascaded multilevel inverter for transformerless sag/dip compensation is investigated. This topology is investigated as a cost-effective means for series sag compensation by eliminating the large injection transformer and output filter components that are used in conventional series injection devices.

Cascaded Multilevel Inverter for Industrial Applications
2013This paper work presents certain Sequential Switching Hybrid Modulation strategies and compared for single phase multilevel inverters. Hybrid modulation represents the combination of fundamental frequency and multilevel sinusoidal modulations and designed for performance of the well-known alternative phase opposition disposition (APOD).

Power sharing improvement in cascaded multilevel inverters
Proceedings of 14th International Power Electronics and Motion Control Conference EPE-PEMC 2010, 2010Several switching strategies have been developed to overcome the unbalanced working period and power sharing in cascaded multilevel inverters, but the power sharing problem is remained unsolved yet. In this paper, a novel switching method which equalizes the modules' power sharing is presented.
