Electronic compensation of inductive voltage dividers and standard voltage transformers
(IEEE, 1999)
A new compensating system is proposed to reduce the ratio error and the phase error of inductive voltage dividers and standard voltage transformers, operating at no load. An electronic amplifier reduces the input current, ...
Low voltage four-quadrant current multiplier: an improved topology for n-well CMOS process
(Springer, 2010-10-01)
An analog CMOS current multiplier building block for low voltage applications using an n-well process is presented. The multiplier equations are derived to proof its linear characteristic, and then a low voltage design is ...

Integrated Local and Coordinated Overvoltage Control to Increase Energy Feed-In and Expand DER Participation in Low-Voltage Networks
(2022-01-01)
Large amounts of active power injection by inverter-interfaced distributed energy resources (DER) is a common cause of overvoltage in low-voltage networks. Hence, local active and reactive power control (i.e., Volt/Watt ...
Effect of seed addition on SnO2-based varistors for low voltage application
(2013-02-01)
The effect of seed addition on the microstructure and non-ohmic properties of the SnO2 + 1%CoO + 0.05%Nb2O5 ceramic-based system was analyzed. Two classes of seeds were prepared: 99% SnO2 + 1%CuO and 99% SnO2 + 1%CoO (mol%); ...

Controle de tensão em redes de baixa tensão com alta penetração de geração fotovoltaica
(Universidade Estadual Paulista (Unesp), 2017-01-30)
Este trabalho apresenta uma proposta de estratégia global de controle de tensão que emprega programação não linear e duas extensões de estratégias de controle de tensão, encontrados na literatura. O principal objetivo ...
Dynamic DC-Link Voltage Control of Back to Back Modular Multilevel Converter for Drive Applications
(IEEE, 2019)
In this work a dynamic control of the dc-link voltage in a hybrid Back-to-Back (BtB) Modular Multilevel Converter for medium-voltage drive applications is presented. The proposed control scheme relates the speed of the ...
