1. Novel Design of a Hybrid Superconducting Fault Current Limiter with Controlled Solid-State Device
Abstract Fault current limiters are essential devices used to protect the power system and its equipment against high levels of fault current, which are growing up due to the increase of new power sources. This paper proposes a novel design of a Hybrid Superconducting Fault Current Limiter (Hybrid SFCL), which is composed basically by thyristors in series wi

2. Contributions to the intelligent electronic control of voltage regulators for systems of energy distribution in 13,8 kV / Contribuições ao controle eletrônico inteligente de reguladores de tensão para sistemas de distribuição de energia em 13,8 kV
The development considered in this work exceeds to the conventional operation until then practised by being based on a microcontrolled electronic circuit that acts on the load of the system for intermediary of 09 taps of regulation (02 of reduction, 06 of rise and the central office) in total independent way and with great speed of reply, rank that the regul

4. Projeto de dispositivo supressor de surto de tensão / Design of voltage surge protective device
This work intends to design a voltage surge suppressor device for telecommunications equipments. The project was conducted with the help of simulation tools. The physical parameters like dopings and dimensions, as well as structures with and without emitter shorts were studied in order to understand their influence on the device behavior and to establish i

5. Locomotivas de C.A : uma analise harmonica da corrente
AC thyristor controlled electric traction became very usual around the world. Thyristors provide good control performance but they always cause problems to the traction electric system. Overvoltages may arise in the contact line feeding the locomotive and also harmonics generated in the thyristors may affected the grid to which the whole system is connected.
