This paper addresses the inverter nonlinearity of a three-level T-type inverter. The main
causes of the nonlinearity are pulse shaping, pulse skipping due to narrow pulses for the …

The three-level neutral-point-clamped inverter used in the variable frequency system has the
characteristics of a wide frequency range, and the pulsewidth modulation (PWM) strategy …

Existence of dead time that makes the ultimate terminal voltage being inconsistent with the
modulation voltage, is recognized as the main reason for leading output voltage distortion …

In this article, it is discovered that when the switching frequency increases, the current
source rectifier (CSR) will suffer from a grid-side current distortion problem at the sector …

This paper describes a narrow pulse suppression method that is called hybrid modulation
strategy for T-type neutral point clamped (TNPC) three-level converters. Conventional …

There is a wide application prospect of Nearest level pulse width modulation (NL-PWM) in
cascaded H-bridge (CHB) converter, however, it will produce narrow-and error-pulse in the …

L'électronique de puissance est un des domaines technologiques ayant connu le plus
d'innovation durant les 40 dernières années. Les avancées majeures effectuées dans les …

hat work investigates the compatibility of voltage balancing algorithm and multilevel
modulations of a three phase modular multilevel converter (MMC). A study of the “Reduced …

Over the past few decades, the fast development of high switching frequency power
electronics drives towards wider application of voltage source inverters in AL power …

Even though the neutral point potential (NPP) balance problem of three-level neutral-point-
