New family of zero-current-switching PWM converter
(1999-12-01)
A new family of dc-to-dc pulse-width-modulated (PWM) converters is presented. These converters feature soft-commutation at zero-current (ZC) in the active switches. The new ZCS-PWM Boost and new ZCS-PWM Zeta converters, ...

Distributed Current Control of Cascaded Multilevel Inverters
(IEEE, 2019)
Multilevel inverters are widely used in the medium voltage energy market. Among them, the Cascaded H-Bridge (CHB) and Modular Multilevel Inverter (MMC) stand out for their modular hardware, which allows the easy replacement ...
Fault-Tolerant Reconfiguration System for Asymmetric Multilevel Converters Using Bidirectional Power Switches
(IEEE, 2009)
Asymmetric multilevel converters can optimize the number of levels by using H-bridges scaled in the power of three. The shortcoming of this topology is that the H-bridges are not interchangeable, and then, under certain ...
Fault Tolerant Reconfiguration System for Asymmetric Multilevel Converters Using Bi-Directional Power Switches
(IEEE, 2007)
Asymmetric multilevel converters can optimise the number of levels by using H bridges scaled in power of three. The shortcoming of this topology is that the H bridges are not interchangeable and then, under certain faulty ...
Optimal asymmetry for cascaded multilevel converter with cross-connected half-bridges
(IEEE, 2015)
DC-AC conversion has been revolutionized by multi-level converters due to their high power quality, high modularity and high voltage operation with standard semiconductors. New multilevel topologies, voltage asymmetries ...
Drivers de baixo custo para acionamento de inversores trifásicos
(Seminário de Iniciação Científica e Tecnológica da UTFPR, 2020)
Driver eletrônico com seis saídas isoladas para transistores de potência do tipo IGBT
