The increase of transmission frequency reveals more merits than low-or medium-frequency
distribution among different kinds of power applications. High-frequency inverter serves as …

This paper deals with the design methodology for cascaded multilevel converter (CMC)-
based transmission-type STATCOM (T-STATCOM) and the development of a±12 MVAR, 12 …

A multilevel topology with medium-frequency ac link for medium-voltage grid integration of
utility photovoltaic (PV) plants is discussed in this paper. A megawatt-scale PV plant is …

The purpose of neutral-point voltage balancing algorithms in the three-level neutral-point
clamped (3L-NPC) topology is to eliminate the voltage unbalance of top-and bottom-side dc …

Modular multilevel converters (MMCs) have become increasingly interesting in dc-dc
applications, as there is a growing demand for dc-dc converters in high-voltage applications …

A new topology for multilevel DC–AC conversion is presented in this study. It consists of
isolated symmetric input DC sources alternately connected in opposite polarities through …

This paper presents theoretical analysis of a network fault tolerant hybrid cascaded
multilevel converter when operated as one unit using multilevel pulse width modulation. The …

This article is devoted to the Multi-level inverters review and in particular to the form and
function of modular multilevel inverters (MMI), with their different topologies, modulation …

In this study, firstly a new basic unit is proposed for multilevel converters. The proposed
basic units are used as building blocks to form a cascaded multilevel converter. In other …

This paper presents an optimized switching strategy to reduce the dc-link ripple current for
three-level photovoltaic (PV) inverters. The large electrolytic capacitors are commonly used …
