Reduced Multisource Switched-Capacitor Multilevel Inverter Topologies
(2022-12-01)
Multisource switched-capacitor multilevel inverters are proper topologies when multiple dc sources are available as renewable energy sources. However, these multilevel inverters have the main drawbacks of requiring a large ...
Desenvolvimento de conversores de cinco níveis com capacitor chaveado e grampeamento ativo do ponto neutro
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2022-06-28)
This work aims to propose a five-level converter topology. The proposed converter
uses the switched capacitor concept with an active neutral point clamped structure, with
one floating capacitor per phase and only one ...
A 15-Level Switched-Capacitor Multilevel Inverter Structure with Self-Balancing Capacitor
(2022-03-01)
In this brief, a new switched capacitor-based structure is presented for a single-phase multilevel inverter. The proposed structure is capable of boosting the input voltage and producing fifteen voltage levels at the output ...
Zero-Current Switching (ZCS) for a High Step Ratio Modular Multilevel dc-dc Converter with wide voltage range operation
(IEEE, 2020)
The rise of new dc technologies is pushing the development of highly efficient dc-dc converters, especially at high voltage and high step ratio. Modular multilevel converters (MMCs) are an attractive alternative because ...
