Sensorless active damping strategy for parallel interleaved voltage source power converters with LCL filter
(IEEE, 2017)
info:eu-repo/semantics/conferenceObject,
Grid-connected pulse-width modulation converters with LCL filters are widely extended as an interface for renewable energy generating systems. Those filters arise stability issues due to the filter resonance, which, must ...

MIMO based decoupling strategy for grid connected power converters controlled in the synchronous reference frame
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
Power converters are frequently connected to the grid through a LCL filter, controlling its power transfer through a current control loop in the synchronous reference frame. In this reference frame, cross coupling terms ...
Modeling solar cavity receivers: a review and comparison of natural convection heat loss correlations
(Elsevier, 2015)
info:eu-repo/semantics/conferenceObject,
As the main difficulty of modeling cavity receivers is determining natural convection heat losses, this paper presents a survey of the different natural convection correlations developed by several authors to model natural ...
Multisampled-capacitor-voltage active damping for parallel interleaved grid connected voltage source converters with LCL filter
(IEEE, 2017)
info:eu-repo/semantics/conferenceObject,
Parallel interleaved converters for high power renewable energy systems present stability issues at the LCL resonance frequency. A multisampled measurement and filtering strategy is proposed to stabilize the system based ...
On the limits of the capacitor-voltage active damping for grid-connected power converters with LCL filter
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
Active damping strategies are widely extended to avoid stability issues at the LCL filter resonant poles in grid-connected voltage source converters. The capacitor voltage derivative active damping effectively damps the ...
Micro-drilled optical fiber for enhanced laser strain sensors
(SPIE, 2019)
info:eu-repo/semantics/conferenceObject,
In this work, we present an experimental measurement of temperature and strain sensitivities of a micro-drilled optical
fiber (MDOF). The MDOF consisted of a quasi-randomly distributed reflector along a single mode fiber ...
Multiplexing optical fiber Fabry-Perot interferometers based on air-microcavities
(SPIE, 2019)
info:eu-repo/semantics/conferenceObject,
In this work we demonstrate the multiplexing capability of new optical fiber Fabry-Perot interferometers based on airmicrocavities using a commercial FBG interrogator. Three optimized air-microcavity interferometer sensors ...
Strengthened ordered directional and other generalizations of monotonicity for aggregation functions
(Springer, 2018)
info:eu-repo/semantics/conferenceObject,
A tendency in the theory of aggregation functions is the generalization of the monotonicity condition. In this work, we examine the latest developments in terms of different generalizations. In particular, we discuss ...
DC capacitance reduction in three-phase photovoltaic inverters by using virtual impedance emulation
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
DC voltage regulation in grid-connected three-phase PV inverters is a fundamental requirement. In order to reduce the influence of the PV non-linear behavior and ensure stability in the whole operating range, the input ...
