Feasibility of Electronic Tap-Changing Stabilizers for Medium Voltage Lines-Precedents and New Configurations
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009)
Thyristor-based onload tap-changing ac voltage stabilizers are cheap and robust. They have replaced most mechanical tap-changers in low voltage applications from 300 VA to 300 M. Nevertheless, this replacement hardily ...
Projeto de uma referência de tensão com baixa susceptibilidade a interferência eletromagnética (EMI)
(Universidade Estadual Paulista (Unesp), 2011-08-05)
Referências de tensão integradas com baixa sensibilidade à temperatura, tensão de a- limentação e eventos transitórios são componentes críticos na maioria dos circuitos integra- dos. Neste trabalho, além das restrições ...
