XIV Conferência Internacional de Eletricidade Atmosférica

A Conferência Internacional de Eletricidade Atmosférica (ICAE) é o maior evento mundial sobre raios, realizada desde 1954. Em 2011 acontece pela primeira vez no Hemisfério Sul, na cidade do Rio de Janeiro, entre os dias 7 e 12 de agosto.

Abordará os aspectos técnicos e científicos associados à ocorrência de fenômenos elétricos na atmosfera, em particular as descargas atmosféricas ou raios. O principal objetivo é apresentar pesquisas realizadas em todo o mundo e o desenvolvimento tecnológico na área.

A ICAE 2011 será a maior conferência sobre raios da história, com um número recorde de 317 trabalhos completos (a marca até então era de 300 trabalhos na conferência de 1992) e de 37 países participantes (superando os 30 países na China em 2007). O Brasil é o país com maior número de trabalhos a serem apresentados (77). Além dos trabalhos técnicos, estão previstas sete palestras especiais

Distúrbios da energia elétrica – Conceitos e implicações
30 de maio de 2011 de 10:00 às 11:00
Neste webinar serão apresentados os conceitos básicos dos principais distúrbios da energia elétrica que afetam o funcionamento de equipamentos e causam perdas de produção e financeiras. Variação de tensão, interrupção, harmônicas e inter-harmônicas, flicker, surtos e ruídos, entre outros tópicos. Discussão das formas de correlacionar os distúrbios x perdas x investimento em solução. Este Webinar é indicado particularmente para aqueles que desejam ter acesso aos conceitos introdutórios sobre o assunto.

ANÁLISE COMPARATIVA DE CONVERSORES MONOFÁSICOSAPLICADOS À CORREÇÃO DE FATOR DE POTÊNCIA

ABSTRACT
Master Dissertation

Programa de Pós-Graduação em Engenharia Elétrica
Universidade Federal de Santa Maria
ANÁLISE COMPARATIVA DE CONVERSORES MONOFÁSICOS
APLICADOS À CORREÇÃO DE FATOR DE POTÊNCIA
AUTHOR: ENG. FERNANDO BELTRAME
RESEARCH SUPERVISOR: DR. ENG. JOSÉ RENES PINHEIRO
Santa Maria, August 12th, 2009.
This work presents a study and a comparative analysis of high power single-phase
converter applied to power factor correction in according to the international standards IEC
61000-3-4 (harmonics limitation) and CISPR 22 (electromagnetic interference limitation) for
high power applications. The converters studied were the conventional boost converter, the
interleaved boost converter, with two cell operating with a delay angle of 180º between each
other, and the dual boost converter. Such converters are used in front-end modules of
information technology equipment. All converters have the same input and output voltage and
the same input current. The converters were projected to provide the same total input
harmonic distortion (THD), with the idea of using the same input filter. Implementation of the
control laws was performed through a digital control with the use of a 16 bits microcontroller.
All converters were, first of all, studied and presented in this dissertation. The
analyzed parameters for comparison were: power factor, total harmonic distortion (THD),
semiconductor losses and magnetic losses, heat-sinks volume and magnetics volume,
conducted electromagnetic interference, performance and costs.
