Revisão de métodos de correção de fator de potência e projeto de um conversor boost PFC
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de EletrônicaEngenharia EletrônicaUTFPR, 2021-11-23)
Improving the conscious use of energy and its efficiency, the work proposes a resolution of how powers are dissipated in loads in alternating current and how the power factor can be applied to increase the efficiency of a ...
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, ...
Reconfiguracao de sistemas de distribuicao radiais utilizando o criterio de queda de tensao
(2000-09-01)
Network reconfiguration in distribution systems can be carried out by changing the status of sectionalizing switches and it is usually done for loss minimization and load balancing. In this paper it is presented an heuristic ...

Quantitative end qualitative analysis of the electrical activity of rectus abdominis muscle portions
(Electromyogr Clin Neurophysiol, 2003)
The purpose of this study was to investigate the electrical behavior pattern of the Rectus abdominis muscle by qualitative and quantitative analysis of the electromyographic signal obtained from its superior, medium and ...
Controladores repetitivos aplicados a filtros ativos de potência sob variações de carga e de frequência da rede
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilPrograma de Pós-Graduação em Engenharia ElétricaUTFPR, 2014-10-03)
This work presents the development and modification of techniques to reduce the effects of load variation and mains frequency deviation in repetitive controllers applied to active power filters. To minimize the effects of ...
