Energy Balancing Improvement of Modular Multilevel Converters under Unbalanced Grid Conditions
(Institute of Electrical and Electronics Engineers, 2017-08)
This paper presents a feedback/feed-forward control strategy to improve the voltage balancing of modular multilevel converters (MMCs) under unbalanced grid conditions. The inclusion of a feed-forward compensation improves ...
A Noncontact Voltage Measurement System for Power-Line Voltage Waveforms
(Institute of Electrical and Electronics Engineers, 2019-07)
This paper presents the design and implementation details of a complete noncontact (NC) voltage acquisition system, which allows the measurement of power-line voltage waveforms without galvanic contact. The system is ...

Adaptive Control Strategy for VSC-Based Systems under Unbalanced Network Conditions
(Institute of Electrical and Electronics Engineers, 2010-12)
A new adaptive control strategy, intended to improve the ride-through capability of HVDC systems under unbalanced network conditions and parameter uncertainties, is introduced. The proposed strategy resorts to a model ...
Charge-voltage relationship of the first impulse corona in long airgaps
(IOP Publishing, 2005-07)
This paper investigates the relationship between the charge Qi of the first impulse corona and the associated inception voltage Ui for a 1 m point-plane airgap submitted to impulse voltages. Experimental studies under both ...
