An Integrated Converter and Machine Control System for MMC-Based High-Power Drives
Mauricio Espinoza-B.,Roberto Cardenas,Jon Clare,Diego Soto-Sanchez,Matias Diaz,Enrique Espina,Christoph M. Hackl +6 more
TL;DR: A new integrated control scheme is discussed to regulate the voltage fluctuations of the modular multilevel converter, based on closed-loop vector-control of the Voltage fluctuations, maintaining them inside a predefined threshold.

Model-Predictive-Control-Based Capacitor Voltage Balancing Strategies for Modular Multilevel Converters
Andres Mora,Matias Urrutia,Roberto Cardenas,Alejandro Angulo,Mauricio Espinoza,Matias Diaz,Pablo Lezana +6 more
TL;DR: Two capacitor voltage balancing strategies for modular multilevel converter (MMC) applications are presented, designed to efficiently solve a constrained optimal control problem, where the predicted capacitor voltage errors are included in the cost function with the demanded output voltage of a cluster being forced through an equality constraint.
Journal ArticleDOI
A New Space-Vector-Modulation Algorithm for a Three-Level Four-Leg NPC Inverter
TL;DR: In this paper, a three-dimensional space vector modulation (SVM) algorithm is proposed for power conversion systems interfaced to four-wire supplies, and a comprehensive analysis of the algorithm implemented on a threelevel, four-leg neutral-point-clamped converter is provided.
Journal ArticleDOI
Fast Convergence Delayed Signal Cancellation Method for Sequence Component Separation
TL;DR: In this letter, a DSC methodology with fast convergence time is proposed and it is shown that an improved separation of the positive and negative sequences is feasible.
