Journal ArticleDOI
Control of Wind Energy Conversion Systems Based on the Modular Multilevel Matrix Converter
Matias Diaz,Roberto Cardenas,Mauricio Espinoza,Felix Rojas,Andres Mora,Jon Clare,Patrick Wheeler +6 more
TL;DR: The proposed control strategies enable decoupled operation of the converter, provide maximum power point tracking capability at the generator side, grid code compliance at the grid side (including low-voltage ride-through control) and good steady state and dynamic performance for balancing the capacitor voltages in all the clusters.
Journal ArticleDOI
An Enhanced $dq$-Based Vector Control System for Modular Multilevel Converters Feeding Variable-Speed Drives
TL;DR: A new control system, based on cascaded control loops and a vector-power-voltage model of the M C-based drive laboratory prototype with 18 power cells, is proposed and experimental results obtained are presented.
Journal ArticleDOI

Muirhead,Felipe Murgas,Francesco Pepe,N. C. Santos,D. Segransan,Jeffrey C. Smith,P. Tenenbaum,Guillermo Torres,Stéphane Udry,M. Vezie,J. Villansenor +35 more
TL;DR: In this paper, the authors measured the masses of the known transiting planets in the L 98-59 system using precise radial velocity (RV) measurements taken with the HARPS spectrograph.
Journal ArticleDOI

Zapata,Lyu Abe,François-Xavier Schmider +28 more
TL;DR: In this article, the authors study ten years of European Southern Observatory/High Accuracy Radial Velocity Planet Searcher (HARPS) high-resolution spectroscopic data of β Pictoris.
Journal ArticleDOI
HD 1397b: a transiting warm giant planet orbiting a V = 7.8 mag sub-giant star discovered by TESS
Rafael Brahm,Néstor Espinoza,Andrés Jordán,Thomas Henning,Paula Sarkis,Matias I. Jones,Matias Diaz,James S. Jenkins,Leonardo Vanzi,A. Zapata,Cristobal Petrovich,Diana Kossakowski,Markus Rabus,Pascal Torres +13 more
TL;DR: In this paper, the authors reported the discovery of a transiting planet first identified as a candidate in Sector 1 of the Transiting Exoplanet Survey Satellite (TESS), and then confirmed with precision radial velocities.
