Projecto e construção de um transformador de potência supercondutor
Dissertação para obtenção do Grau de Mestre em Engenharia Electrotécnica e de Computadores
Paulo Rogério Santos Figueira, Faculdade de Ciências e Tecnologia, Universidade Nova de Lisboa.
Resumo
Os transformadores de potência baseados em supercondutores de alta temperatura têm revelado potencial para diversas aplicações práticas, proporcionando benefícios aos níveis económico, ambiental e operacional. Na presente dissertação, dois protótipos de transformadores monofásicos de 650 VA foram dimensionados, desenvolvidos, ensaiados e caracterizados: um convencional, com enrolamentos de cobre, e outro com o mesmo enrolamento de cobre no primário mas com o secundário composto por fita supercondutora de alta temperatura. Os dois protótipos foram comparados em relação às propriedades magnéticas, perdas, parâmetros eléctricos e rendimento, apresentando e interpretando os resultados obtidos. Foram ainda efectuadas medições para determinar a corrente crítica em AC da fita supercondutora. Os resultados foram comparados com os da corrente crítica obtida em DC para a mesma fita.

ALL NEWS DELLS OptiPlex™ desktops and Precision™ workstations REQUIRE PURE SINE WAVE UPS's?
DELL™ OPTIPLEX™ 390 TECHNICAL GUIDEBOOK —FINAL
POWER
NOTE: These form factors utilize a more efficient Active Power Factor Correction (APFC) power supply. Dell recommends only Universal Power
Supplies (UPS) based on Sine Wave output for APFC PSUs, not an approximation of a Sine Wave, Square Wave, or quasi-Square Wave. If you
have questions, please contact the manufacture to confirm the output type.
Power Protection & Back-up
In the case of a power outage, be prepared with an Uninterruptible Power Supply (UPS) that can provide business continuity to prevent critical data loss. For Dell OptiPlex™ desktops and Precision™ workstations that utilize Active Power Factor Correction (APFC) power supply units, Dell recommends Universal Power Supplies (UPS) based on Sine Wave output, not an approximation of a Sine Wave, Square wave, or quasi-square wave (see UPS technical specifications).
