New five-level active neutral point clamped converter [PDF]

open access: yes2013 IEEE Energy Conversion Congress and Exposition, 2013
Multilevel converters are a proven solution for medium voltage and high power applications including renewable energy conversion. Developing 6.6 kV converters is a key goal for the wind turbines industry. Considering the voltage rating of commercially available semiconductors, five-level converters are necessary to reach 6.6 kV.

Modulation Strategy for Multiphase Neutral-Point-Clamped Converters [PDF]

open access: yesIEEE Transactions on Power Electronics, 2016
This paper presents a novel modulation strategy for n-phase neutral-point-clamped (NPC) converters. The proposed modulation strategy is able to control and completely remove the low-frequency neutral-point (NP) voltage oscillations for any operation point and load types. Even when unbalanced and/or nonlinear loads are considered, the NP voltage remains

A Three-level Neutral-Point Clamped Dual-Output Converter

open access: yes2021 IEEE Energy Conversion Congress and Exposition (ECCE), 2021
This paper introduces a novel three-level dual-output neutral-point clamped converter. The proposed topology has both the advantages of a reduced power component count and complete independent control of its outputs. The converter is operated using Finite-Control-Set Model Predictive Control (FCS-MPC).
