A simple and efficient off-optical axis electro-optic voltage sensor
(2014-03-12)
Sinusoidal high-voltage measurements at 50/60 Hz are very important since, at present, power delivery systems use this kind of low frequency waveforms. It is well known that conventional instrument transformers, based on ...
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 ...
A low-voltage low-power analog memory cell with built-in 4-quadrant multiplication
(Institute of Electrical and Electronics Engineers (IEEE), 2003-04-01)
An accurate switched-current (SI) memory cell and suitable for low-voltage low-power (LVLP) applications is proposed. Information is memorized as the gate-voltage of the input transistor, in a tunable gain-boosting ...

A novel HPF voltage source rectifier for variable speed refrigeration systems
(IEEE, 2006-01-01)
A novel single-phase voltage source rectifier capable to achieve High-Power-Factor (HPF) for variable speed refrigeration system application, is proposed in this paper. The proposed system is composed by a single-phase ...
