Efficient implementation of DVR's control
2009 IEEE Power & Energy Society General Meeting, 2009This paper reports the detailed implementation of a three-phase dynamic voltage restorer (DVR). Such devices have gained popularity among the PWM-based compensation series devices. Two cases are studied: balanced and unbalanced voltage sags, which are the most frequent disturbances.

Comparison of GMP and DVR models
2018 International Workshop on Integrated Nonlinear Microwave and Millimetre-wave Circuits (INMMIC), 2018In this paper, we present a comparative study on the behavior of digital predistortion (DPD) models, in order to mitigate the nonlinear distortions of RF power amplifiers. The models compared are Generalized Memory Polynomial (GMP) and Decomposed Vector Rotation (DVR).

Study of sag compensation with DVR
MELECON 2006 - 2006 IEEE Mediterranean Electrotechnical Conference, 2006Voltage dip analysis is a complex stochastic issue, since it involves a large variety of random factors: type of short-circuits in the power system, location of faults, protective system performance and atmospheric discharges. Among all categories of electrical disturbances, the voltage dip (sag) and momentary interruption are the nemeses of the ...

A framework f or calculating fundamental DVR performance limits
2009 Digest of Technical Papers International Conference on Consumer Electronics, 2009New systems have emerged that deliver hundreds of megabits per second of video to the home. This, coupled with deeper penetration of in-home video networking, will create demand for digital video recorder (DVR) performance to scale up dramatically as well.

No-sag industrial power with DVRs
IEEE Potentials, 2007Voltage sag is a relatively long-duration drop in line voltage. It is defined as a decrease between 0.1 and 0.9 per unit (pu) in alternating-current line voltage for durations of 0.5 cycles to 1 minute, where "per unit" is a fraction of the base voltage.
