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 novel up-converting mechanism based on double impact for non-linear piezoelectric energy harvesting
(IOP Publishing, 2020-11-01)
In this paper we show the importance of double impact in an up-converting mechanism by usinga resonant low-frequency driving beam across a high-frequency piezoelectric beam, to enhancethe electrical output power in a ...

High-performance control of a three-phase voltage-source converter including feedforward compensation of the estimated load current
(Pergamon-Elsevier Science Ltd, 2009-08)
In this paper a new control strategy for voltage-source converters (VSC) is introduced. The proposed strategy consists of a nonlinear feedback controller based on feedback linearization plus a feedforward compensation of ...
Modeling, control, and reduced-order representation of modular multilevel converters
(Elsevier Science Sa, 2018-10)
This paper presents a reduced-order model of the modular multilevel converter (MMC) for electromechanical transient simulations and small-signal analysis. The MMC model is firstly developed in detail; then, simplifications ...
Optimization of an ac-dc transfer step-up scheme
(Institute of Electrical and Electronics Engineers, 2007-04)
A set of statistical tools is proposed for the optimization of an alternating current-direct current voltage or current transfer step-up scheme. These tools are used to remove standards with level dependence and instabilities ...
Isolated Buck/Boost Bidirectional DC-Three Phase Topology
(Institute of Electrical and Electronics Engineers, 2016-06)
In this paper a new topology, isolated Buck/Boost bidirectional DC-AC three phase, for interconnecting a DC micro grid with conventional three-phase AC network, is presented. Its operating principle is explained, and a ...
