A new design methodology for multipulse rectifiers with Delta auto-connected transformers and a retrofit application in Adjustable Speed Drives (ASDs)
(2012-12-01)
Multipulse rectifiers can replace a conventional six pulse three-phase rectifier (diode bridge) providing a DC voltage with low ripple, low Total Harmonic Distortion of current (THDi) and a high Power Factor (PF). In this ...

Proposta de um retificador ajustável para transmissão de energia sem fio e metodologia de projeto de retificadores differential drive baseada em simulações
(Universidade Federal de Santa MariaBrasilCiência da ComputaçãoUFSMPrograma de Pós-Graduação em Ciência da ComputaçãoCentro de Tecnologia, 2022-02-09)
This work presents a simulated model of a rectifier with adjustable efficiency for wireless
power transfer systems. The adjustment is possible through a control block that, by the
combination of 3 differential drive ...
A fuzzy-controlled active front-end rectifier with current harmonic filtering characteristics and minimum sensing variables
(1999)
A control strategy which allows conventional voltage-source current-controlled (VSCC) pulsewidth modulation (PWM) rectifiers to work simultaneously as active power filters is presented. The proposed control strategy also ...
Implementação de uma fonte de tensão ajustável baseada em um retificador monofásico com tiristores
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de EletrônicaEngenharia EletrônicaUTFPR, 2017-06-12)
Most power distributors provide 60 Hz sine-wave voltage, however, many appliances require continuous voltage to operate. The aim of this work is to study and implement an adjustable source based on a fully controlled full ...
NOVEL ISOLATED MULTI-PULSE RECTIFIERS WITH LOW CURRENT DISTORTION USING THREE-PHASE HALF-CONTROLLED BOOST CONVERTERS
(Ieee, 2015-01-01)
Since the AC-DC conversion is widely spread in power sources, this work proposes a novel strategy of multi-pulse topologies, associated to the half-controlled boost-based rectifier, which has the follows main advantages: ...
