Kernel hautapen dinamikoa Optimizazio Bayesiarrean
(UEU, 2015)
In Bayesian Optimization, when using a Gaussian Process prior, some kernels adapt better than others to the objective function. This research evaluates the possibility of dynamically changing the kernel function based on ...
Review of computational parameter estimation methods for electrochemical models
(Elsevier Ltd, 2021)
Electrochemical models are an incipient technique for estimation of battery cells internal variables, useful for cells design or state of function optimization. One of the non-trivial procedures that allow the use of this ...
Analytical model to calculate radial forces in permanent-magnet synchronous machines
(IEEE, 2014)
In permanent-magnet synchronous machines (PMSMs) electromagnetic forces are identified as the principal source of vibrations and noises. In this article, first of all the sources of magnetic forces in PMSMs are analyzed. ...
Radial fan simulations by computational fluid dynamics and experimental validation
(IEEE, 2014)
Fans are commonly used to refrigerate electrical machines when air forced cooling is required. They are rather simple solutions that can considerably improve the thermal performance of electrical machines, so the fan ...
Methodology to Study Demagnetization Risk in Permanent Magnet Machines by Finite Element Method
(IEEE, 2017)
Nowadays the majority of applications are demanding more and more compact, cost effective and robust solutions for their electric drives. In this context permanent magnet synchronous machines are considered as a good ...
Thermal test procedure and analytical model calibration method for electrical machines
(IEEE, 2013)
In this paper a thermal test procedure and a calibration method for lumped parameter models are presented. Analytical models provide fast thermal simulations in comparison with finite element methods (FEM) and computed ...
Analytical model to calculate magnetic flux density in permanent magnet synchronous machines with static eccentricity
(IEEE, 2016)
In this article a general analytical model for the analysis of permanent magnet synchronous machines with static eccentricity is presented. The model is a continuation of [1] and it is based on Fourier time-space series ...
Experimental test bench for testing DC microgrid control strategies
(IEEE, 2017)
During the last decades the number of microgrids and their research have increased notably, as they offer a high versatility for the integration of distributed generation (DG) units and renewable energies. Among the different ...
Comprehensive analysis of voltage balancing techniques for 5L NPC converters
(IEEE, 2013)
The reduced capability of the 5L-NPC Inverter to balance the voltages of the four DC-bus capacitors makes this converter unattractive for real power applications. This is especially true if the load demands active power. ...
Static Current Unbalance of Paralleled SiC MOSFET Modules in the Final Layout
(IEEE, 2020)
Silicon Carbide (SiC) MOSFETs enable enhanced performance of power converters in several applications. Parallel connection of SiC MOSFETs become mandatory for medium power applications due to the current rate of existing ...
