Analysis and Design Guidelines for Current Control Loops of Grid-Connected Converters Based on Mathematical Models
Abad, Gonzalo; Milikua, Aritz (MDPI AG, 2020)Having a method for analyzing and designing regulators of controls that contain many current loops such as active filters is not a trivial task. There can be many parameters of regulators and filters that must be carefully ... -
Current References Limitation Method Considering Voltage and Current Maximums for STATCOMs Providing Simultaneously Reactive Power and Current Harmonics
Abad, Gonzalo; Unamuno, Eneko (IEEE, 2022)This article focuses the analysis on a static synchronous compensator (STATCOM) that operates simultaneously providing reactive power and several current harmonics of different frequencies (active power filter or active ... -
DC-Link Neutral Point Control for 3L-NPC Converters Utilizing Selective Harmonic Elimination PWM
Mazuela, Mikel (IEEE, 2021)Selective harmonic elimination–pulsewidth modulation (SHE–PWM) is a modulation technique widely used to improve the efficiency and harmonic content in medium-voltage high-power converters. Among these converters, the ... -

Abad, Gonzalo; Mazuela, Mikel; Baraia-Etxaburu, Igor; Sanchez-Ruiz, Alain (IEEE, 2012)This paper presents a general comparison procedure for medium voltage - high power multilevel converter topologies and semiconductors, which is mainly based on analyzing the performance limits of the converters output ... -
Power Balancing in Cascaded H-Bridge and Modular Multilevel Converters Under Unbalanced Operation: A Review
Marzo Elguero, Iosu; Barrena, Jon Andoni; Abad, Gonzalo; Muguruza Fernández de Valderrama, Ignacio (IEEE, 2021)Multilevel Voltage-Source Converters (VSC) based on modular structures are envisioned as a prominent alternative for grid and industry applications. Foremost among these are the Cascaded H-Bridge (CHB) and the Modular ... -
Power Capability Boundaries for an Inverter Providing Multiple Grid Support Services
Unamuno, Eneko; Bilbao Ortega, Aitor (MDPI AG, 2020)It is getting more common every day to install inverters that o er several grid support services in parallel. As these services are provided, a simultaneous need arises to know the combined limit of the inverter for those ... -
Reactive power limits of Cascaded H-Bridge STATCOMs in star and delta configuration under negative-sequence current withstanding
Marzo Elguero, Iosu; Barrena, Jon Andoni; Abad, Gonzalo (Elsevier Ltd., 2022)Flexible AC Transmission System devices (FATCS) and in particular Static Synchronous Compensators (STATCOM) play a key role in the evolution of the modern power grids to the future smart grids. The STATCOM is used in an ... -
Reactive Power Limits of Single-Phase and Three-Phase DC-Link VSC STATCOMs under Negative-Sequence Voltage and Current
Marzo Elguero, Iosu; Barrena, Jon Andoni; Abad, Gonzalo (IEEE, 2021)This paper analyzes and compares the reactive power limits of single- and three-phase configured dc-link Voltage Source Converter (VSC) structures for Static Synchronous Compensator (STATCOM) to operate with negative-sequence ... -
Simple voltage balancing method to protect series-connected devices experimentally verified in a 5L-MPC converter
Mazuela, Mikel; Baraia-Etxaburu, Igor (IEEE, 2018)This paper presents a solution for the voltage balance problem of the series-connected devices that can be applied to multilevel converters in which the series-connected devices need to block twice their switched voltage. ... -
Zero-sequence controller requirements and comparison for a delta-CHB STATCOM under unbalanced operation
Marzo Elguero, Iosu; Abad, Gonzalo; Costa Pérez de Iriarte, Juan José; Barrena, Jon Andoni (Elsevier, 2024)Delta-configured Cascaded H-Bridge (DCHB) topology is a suitable alternative for Static Synchronous Compensator (STATCOM) applications. However, under unbalanced voltage and/or current conditions, zero-sequence current ...
