Publikováno v: 2017 Asian Conference on Energy, Power and Transportation Electrification (ACEPT).

Testing and verification of high-level and low-level control, modulation, fault handling and converter co-ordination for modular multilevel converters (MMCs) requires development of experimental prototype converters. In this paper, we provide a a com

Minimum signal modulation scheme based on a single carrier for interleaved operation of parallel phase legs in voltage source converters

Autor: Igor Gabiola, Josep Pou, Vassilios G. Agelidis, Salvador Ceballos, Jordi Zaragoza, Gabriel J. Capella

Publikováno v: IET Power Electronics. 7:1305-1312

Connecting legs in parallel is a common way to increase the output current of a power converter. Interleaving the carriers used to modulate the reference signals for each leg leads to a reduction in the output current ripple without resorting to incr

Current Balancing Strategy for Interleaved Voltage Source Inverters

Autor: Igor Gabiola, E. Robles, Gabriel J. Capella, Josep Pou, Salvador Ceballos, Jordi Zaragoza

Publikováno v: Scopus-Elsevier

The parallel connection of inverter legs is a way to increase the output currents and thus, the converter rated power. The connection is made by inductors and a critical issue is to achieve balance...

Three-Level Converter Topologies With Switch Breakdown Fault-Tolerance Capability

Autor: Igor Gabiola, Josep Pou, Dushan Boroyevich, Jordi Zaragoza, Salvador Ceballos, J.L. Villate, E. Robles

Publikováno v: IEEE Transactions on Industrial Electronics. 55:982-995

This paper presents some modified topologies of the neutral-point-clamped converter. In all of them, the main change consists of adding a fourth leg, which is based on the flying-capacitor converter structure. The aim of this additional leg is to pro

Positive-sequence grid voltage detector for distributed generation systems with no tuning requirements

Autor: Josep Pou, José Luis Ortega Martín, Igor Gabiola, Jordi Zaragoza, E. Robles, Salvador Ceballos

Publikováno v: ICECS

This paper proposes a three-phase positive sequence detector that does not require any parameter to be adjusted. It operates in open loop and there is not any PI controller that needs to be tuned. The scheme includes the use of the Park transformatio

Publikováno v: 2008 IEEE Power Electronics Specialists Conference.

This paper presents a control method to regulate the amplitude of the voltage oscillations that appear in the neutral-point of the three-level diode-clamped converter for some operating conditions. The control is applied to the hybrid modulation tech
