Thresholds Optimization of Decomposed Vector Rotation Model for Digital Predistortion of RF Power Amplifier [PDF]

open access: yesRadioengineering, 2021
In this paper, we propose an efficient approach for optimizing the decomposed vector rotation (DVR) model for digital predistortion (DPD). The DVR model’s basis functions are constructed piecewise by dividing the input space into segments bounded by ...

More stability and robustness with the multi-loop control solution for dynamic voltage restorer (DVR) [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2009
This paper presents the application of dynamic voltage restorers (DVR) on power distribution systems for mitigation of voltage sags/swells at critical loads. DVR is one of the compensating types of custom power devices.

Pion-less effective field theory for atomic nuclei and lattice nuclei [PDF]

open access: yes, 2017
We compute the medium-mass nuclei $^{16}$O and $^{40}$Ca using pionless effective field theory (EFT) at next-to-leading order (NLO). The low-energy coefficients of the EFT Hamiltonian are adjusted to experimantal data for nuclei with mass numbers $A=2 ...

Power Quality Improvement Using DVR [PDF]

open access: yesAmerican Journal of Applied Sciences, 2009
Voltage sags and swells in the medium and low voltage distribution grid are considered to be the most frequent type of power quality problems based on recent power quality studies. Their impact on sensitive loads is severe. The impact ranges from load disruptions to substantial economic losses up to millions of dollars.

A New Dynamic Voltage Restorer with Multi-level Open-end Winding Topology [PDF]

open access: yesE3S Web of Conferences, 2020
In this paper, a variety of main circuit structures of DVR based on open-end winding are presented. Two inverters are connected in series to realize the multi-level structure and simplify the hardware cost. According to the mathematical model of open-end

Intelligent Controlled Dynamic Voltage Restorer for Improving Transient Voltage Quality

open access: yesIEEE Access, 2023
A dynamic voltage restorer (DVR) is developed to stabilize the three-phase load voltage under the sudden grid voltage distortion conditions, including the voltage sag, swell and unbalance.
