Novel modified phase-shift modulation strategy for isolated AC-DC power converters
(Institution of Engineering and Technology, 2020-04)
Different power converter topologies are used to perform the energy exchange between an AC grid and a DC source belonging to a hybrid electric micro-grid. A single-phase single-stage isolated AC-DC power converter is one ...
Evaluation of DC-AC single-phase solid-state transformers
(Institute of Electrical and Electronics Engineers, 2019-11-02)
This work presents an evaluation of three topologies of DC-AC single-phase solid-state transformers, for applications in electric microgrids. The main features of these topologies are galvanic isolation, capability to ...
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 ...
Phase-shifted Pulse Width Modulation with alternate zeros voltage for parallel connection of H-Bridges for High-Current Low-Voltage applications
(IEEE, 2019)
Phase-Shifted Modulation (PSM) applied to multilevel converters is an effective method for reducing the output THD. In this paper, a new unipolar PSM method is proposed to control internal circulating current of a high-current ...
N-step linear phase-shifting algorithms with optimum signal to noise phase demodulation

Z-scan and spatial self-phase modulation of a Gaussian beam in a thin nonlocal nonlinear media
(Journal of Optics, 2011)
The minimum Euclidean distance principle applied to improve the modulation diffraction efficiency in digitally controlled spatial light modulators
(Optical Society Of America, 2010)
Digital addressing of the electrical signal in spatial light modulators, as it is the case in present liquid crystal on silicon (LCoS) displays, may lead to temporal phase fluctuations in the optical beam. In diffractive ...
