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 ...
Fontes CA de potência: contribuição ao estudo e ao desenvolvimento de topologias híbridas
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2012-12-20)
In this thesis an study of AC Power Source (ACPS) topologies that guarantee the synthesis
of high quality voltage waveforms (in comparison to the reference signal) without
penalizing the system efficiency is carried out. ...
Controle de aceleração de uma máquina de vibração eletrodinâmica
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2005-03-24)
This work presents the development of a novel digital acceleration controller for sinusoidal vibration tests using switching-mode AC power source (ACPS) fed electrodynamic vibration machines. The proposed scheme is based ...
High-precision current source using low-loss, single-switch, three-phase AC/DC converter
