A review of project of the controllers for an UPS
(Ieee-inst Electrical Electronics Engineers Inc, 2018-02-01)
This paper presents a classical design methodology, review and comparison between different controllers applied to control the output stage of a UPS single-phase 127V/60Hz of 1kVA in islanded operation. The behavior is ...
A review of project of the controllers for an UPS
(2018-02-01)
This paper presents a classical design methodology, review and comparison between different controllers applied to control the output stage of a UPS single-phase 127V @ 60Hz of 1kVA in islanded operation. The behavior is ...
Projeto e implementação de método para conexão paralela de UPSs com compartilhamento de potência
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2012-08-31)
This work presents the design and experimental implementation of a complete paralleling method to be used for parallel single-phase UPSs connection. There is a algorithm that performs a phase/frequency droop, and a new ...
Design of an 10 kVA-45 A automatic static transfer switch module
(Institute of Electrical and Electronics Engineers, 2014-04-08)
Uninterruptible Power Supplies (UPS’s) are designed to provide emergency power when the main power source fails. To avoid this impact and to protect effectively the loads, one solution is to provide a redundant loading ...
Desenvolvimento de ferramentas computacionais para a análise de perdas em conversores estáticos: aplicação ao cálculo de rendimento de UPSs trifásicas de dupla conversão
(Universidade Federal de Minas GeraisUFMG, 2016-07-28)
Double-conversion UPSs (Uninterruptible Power Supplies) are devices that provide safe and continuous supply to mission-critical systems, in which disturbances or interruptions in power supply can lead to losses or damages. ...
Inversor PWM com controle por modos deslizantes em tempo discreto
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2015-06-02)
This work presents one of the most used topologies of an Uninterruptible Power Supply (UPS) with main focus to the steps of the PWM inverter and control used: Sliding Mode Control in Discrete Time. The PWM inverter with ...
Desenvolvimento de conversor bidirecional isolado para controle de carga e descarga de bancos de baterias
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilPrograma de Pós-Graduação em Engenharia ElétricaUTFPR, 2018-02-21)
The bidirectional and isolated converters discussed in this work are of great interest for applications such as UPS’s (Uninterrupted Power Supply) and hybrid generation power systems. They allow the charging and discharging ...
